I was wondering if I could create a bridge between two wireless interfaces. So that when there is a WAN that filters MAC's, 2 different computers which aren't in the WAN white list can connect to the WAN via me. Is that possible? And how?

Setup : internet -- VirtualBoxHost -- WIFI-switch -- clients
VirtualBoxHost hosts several Virtual Machines and has 2 interfaces. Wan-interface is not used by VirtualBoxHost, but is directly mapped to the Virtual Machine Endian Firewall.
What I want:
Access to VM's for the Wifi-clients AND access from WiFi-clients to VirtualBoxHost.
What I have tried:
- create bridge
- add LAN-interface to bridge
- create tap0
- add tap0 to bridge
Virtual Machine uses tap0
Wifi-clients are connected via LAN-interface, via bridge, to VM's. But my host-machine is not accessible from a WLAN-client and also I can not access a VirtualMachine from my host-machine. A WLAN-client can connect to a VirtualMachine without problem. I think with my bridge the local LAN and the VM's are now connected. How to put also my host-machine in the LAN? As a LAN-client.
Does anybody know how to setup bridge interfaces on fedora 15 (VirtualBox4 interface and my LAN interface)?
View 1 Replies View RelatedThe challenge: I am trying to setup a piece of hardware that is transparent to the network that transfers ip packets between two interfaces without adding a "hop". Details The particular problem I'm having is that one interface is ppp, the other is ethernet. It is trivial to setup a bridge between two ethernet devices but I am having trouble finding anything for ppp<->ethernet.
Here, the ppp link is an internet connection, and the ethernet connection has exactly one device attached. Once the ppp link is negotiated, I want the ppp peer to think it's talking directly with the device on my ethernet interface and I want the device on my ethernet interface to think it's talking directly to the ppp peer.
Current solution: The best solution I currently have is to alter the routing table. When the ppp link is negotiated, I am given an ip address. I add a route that directs everything to that ip address to the eth0 device. I also set a default route to the ppp device. Now, anything that comes from the ethernet side gets forwarded to the ppp side, and anything directed towards my ip address gets forwarded to the eth0 side.
I have a network config as follows:
X.8 <---> X.41 X.40 <--->X.16
where X.8 and X.16 are 2 separate workstations and X.40/X.41 are two interface cards in the same machine. Now I apply brctl bridging in the X.40/X.41 machine by adding both the interfaces to the bridge and thereby connecting X.8 and X.16. This part is working perfect. But there is no connectivity between X.8 and X.41 and when I try to ping at X.8 to X.41 it gives Destination Host Unreachable. Is there a way to achieve this since I require some message to be sent from X.8 to the X.40/X.41 bridge machine.
I am trying to set up a network like this:
Internet <---> Router <---> Debian server <---> Windows PC
I want the server and PC to both have internet access, and I want to be able to forward ports from the router to the server. I know how to configure the server to give the PC internet access, but how would I assign an IP address to the server and give it internet access? I have used a very similar setup a few years ago, but I can't remember how to do this.
Actually i'm doing an ingenior training in SAGEM company, well i'm trying to develop an application which is able ti disturb the IP Network,my idea was is to mount 2 Network Interface Card (NIC) and make a bridge to pass the IP flow and to exploit the firewall Netfilter using iptables command.The application has to import a text file containing a binary array like this one:
0 1 0 : 0 corresponds to iptables -p ip ACCEPT
1 1 1 : 1 corresponds to iptables -p ip DROP
0 0 1
==> So the expected result is to have 5 ip datagrams dropped
My idea was: if 0 --> iptables -A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
if 1 --> iptables -A FORWARD -p ip -m limit --limit-burst 1 -j DROP
The problem was: After executing the application and parsing the text file,
with iptables -L -v: i have
Code:
-A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
-A FORWARD -p ip -m limit --limit-burst 1 -j DROP
-A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
which is logic, but when i sniff with wireshark i find more packets are dropped(6,7 or 8 are dropped), like i had put more DROP rules. and sometimes i found the exact value(usually 5 dropped).
I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.
Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:
(The WiFi is secured with WPA2 Enterprise)
Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
[code]....
The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?
I have two network interfaces in my pc eth0 and wlan0 and a virtual one br0.
router <= eth0 (0.0.0.0) => br0 (192.168.1.10) <= wlan0 (0.0.0.0) => other pc.
On startup of my pc (ubuntu 10.04 server x64), samba bind itself only to loopback network interface, as i can see when i do netstat -an , preventing me to enter in my shares from a remote pc.
Here is my configuration regarding samba network:
Code:
interfaces = 127.0.0.0/8 192.168.1.0/24
bind interfaces only = yes
and my /etc/network/interface
Code:
# The loopback network interface
auto lo
iface lo inet loopback
code....
Any idea fo speed up my bridge configuration or to force samba to wait unitl the bridge is ready?
Just installed Ubuntu 10.10 server and all working great except the wireless interface. The card is an edimax EW-7711ln. I installed ndiswrapper using the driver rt2860.zip found here [URL]. Then I followed this guide to configure /etc/network/interfaces [URL]. I think the driver is loading fine but I can't connect to the access point. Here is some debugging output...
Code:
peter@Peter-Server~$: route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
Code:
peter@Peter-Server~$: iwconfig .....
So I can scan and see the accesspoint with ssid alleycat but I can't connect. I tried disabling all security to see if it was a problem with my key or some encryption settings but even that didn't work. So frustrating because it seems close to working I must be doing something silly. Incase anyone is wondering why I am running a server off a wireless interface, its just a LAMP development server on my home network.
The following is my setup. wireless server (ip of this server is 192.168.1.1) -- target board ( wireless client [ip of this is got for wireless server is 192.168.1.3 ] , bridge (192.168.36.1) )-- linux pc ( 192.168.36.3) as show above i have target board for that i have a wireless interface and a linux pc is connected to target board.now the ips are like this for linux pc 192.168.36.3 and my target board bridge ip s 192.168.36.1
my wireless interface got ip from another server like 192.168.1.3 ,now if i do ping on my target board for 192.168.1.1 it goes through wireless interface to the 192.168.1.1 wireless server.but when i do the same from target board connected linux pc its not pinging from linux pc i could able to ping to 192.168.1.3 but not 192.168.1.1 .I think i need to write a iptable rule properly on my target board to forward the 192.168.1.* packtes to wireless interface.
I've been having issues setting up the wireless interface on my Ubuntu server (command-line only, no GUI) and I can't seem to get it working. It seems as though the card is recognized, the drivers are installed and the interface is up, but it fails to connect. I have no idea where I'm going wrong. I have WPA and a MAC filtering setup on my wireless router. An exception has been made for this PC's MAC address and I've manually entered the connection details into /etc/network/interfaces.

I've used Fedora 11 and 12, and I found autoten which automatically installs a lot of necessary software and provides an easy GUI interface to do so. I switched to Ubuntu Karmic recently and now I'm working on customizing all the bugs that come with my computer. So far, I've fixed compiz-fusion, the sound problem with ALSA, as well as customizing the theme to the way I like it (by fixed I don't mean it was a reported Launchpad bug, but just that I customized it to my liking or it wasn't previously working on my laptop and it is working now).
So my question is, am I able to (even though my knowledge is limited), able to make some sort of batch script that will automatically apply the changes I wish every time I update my kernel? Or, just for simplicity's sake, I may stay with 9.10 for a while and have this script to apply my changes if/when I have to uninstall/reinstall. I know it's fairly simple to make a batch file in Windows, so I'm hoping it will be just as easy in Linux. (I know, comparing apples to oranges).
I've got a server that has bond0 and bond1 setup. I'm documenting some things in case I need to failover and bring up my secondary server up as primary... I just need to know if simply creating the interface ifcfg-bond0:0 with a new IP address obviously of the crashed system,,, is all that needs done or do I need to load bond0:0 module in /etc/modules.conf also?
View 1 Replies View RelatedI have an old laptop, which doesn't work, as the hard drive died, and can't be detected. I only recently considered trying ubuntu, so I put in the live CD, and it started, although it was very slow. Wired Internet worked, but of course there was nowhere to install drivers for wifi.
When I want to connect my Xbox 360 to the internet, the only solution I have currently is to use my working laptop. In windows, I rightclick on both the wifi and ethernet, and bridge them.
Now, this isn't a great solution, because it means nobody else can use the laptop at the same time, so my family basically say I can only use it when nobody else wants to. Which is never. So it occurred to me that since I'd only need to use the ethernet port and the wifi card, I could set it up as a permanent solution to my gaming needs. Obviously a Live CD wouldn't work; it would have to be a live USB. I can easily get that sorted, but is this viable? I don't know if bridging the connections is viable in Ubuntu, but I'm sure there must be some way, considering how versatile it is.
In case it helps, my old laptop is an Inspiron 1525, with Broadcom wifi card. My new laptop (although I doubt this has any relevance) is an Inspiron 1545.
PS - Is 'wireless bridge' the correct term? It sounded about right when I typed the title.
I am trying to connect networks connected via locked down wireless routers. Here is the setup:
Internet <-> eth0 - server - eth1 providing DHCP <-> hub <-> wired clients & to WiFi router with NAT & DHCP <-> WiFi clients.
I want the wired clients and the WiFi clients to be able to talk to each other directly, but the locked down WiFi router (meraki) is in the way. the wired clients get their IP address from the server, the wireless clients get theirs from the meraki WiFi router. I can't reconfigure the WiFi router to bridged mode without paying meraki a sizeable annual license fee. What options are out there to get through the WiFi router? I came across OpenVPN and ethernet bridging, but broke networking on the server when trying to configure the br0 interface. I followed these instructions: [URL]
I have a Windows 7 machine which is having issues with a Linksys Rangeplus wireless card, specifically kernel dumps every couple of hours. I have an old (really old) tower sitting in my room which I would like to turn into a wireless bridge so that I could connect the windows box to the internet without dealing with the blue screens. I plan on using Knoppix as I have it available already, but if it would be easier with another distro I can always download it. If this doesn't work I'm going to have to buy an old WRT54G offline and convert that with DD-WRT...
View 3 Replies View RelatedI have spent the last 24 hours trying to work a wireless bridge (a D-Link DAP-1522) into my network configuration. It would connect to our gateway here at home (some 2WIRE piece of garbage AT&T hands out, but I digress), and two computers (an Ubuntu Desktop and an Ubuntu Server) would connect via the bridge.
The bridge SEEMS to connect to the router, and indeed, the Ubuntu Desktop PC is able to access the internet. The server, however, is not, and neither computer can communicate with the other (ping, SSH, etc.) furthermore, the router recognizes the presence of these two computers on some level, but does not seem to know their IP addresses (I assume this is related to the computers' inability to communicate).
Before I get too far into this, here are a few links/items for the sake of clarity. The first is a shoddy diagram of my (proposed) network topology, for all of you out there who, like myself, understand things visually:[url]
This is the output from running "ifconfig eth0" on the Ubuntu Desktop PC, which sits behind the bridge. The PC is connected, and can ping hosts across the Internet, but can only ping the router locally (that is, it can't ping any other device in the house, on either side of the bridge):
Code:
The router uses wireless encryption, not MAC addresses, to restrict access/traffic, and all wireless devices (including the bridge) have been provided with the proper credentials. There shouldn't be any devices being denied access on account of their MAC address. In fact, the router's control panel lists the PC and the Server among the recognized devices (even lists their MAC addresses), but provides no IP address and always considers the two computers to be "offline." And yet, I am writing this very post from the Ubuntu PC. Sigh.
I am very comfortable with computers, and reasonably comfortable with Ubuntu/Linux and the Linux command line -- I've been using the operating system for just over a year now -- but networking issues have always been perched right on the edge of my understanding. In short, it's likely this issue has more to do with me than it does with the hardware itself (although the more forums I browse, the more I start to doubt this bridge...).
before i used Ubuntu(i was hiding under a rock) i had my wireless network and Ethernet bridged so that i would be able to broad cast my network printer to the home network. i switched to Ubuntu and it is rather annoying to have to shutdown Ubuntu and boot windows just to print a document

View 6 Replies View RelatedI have a wireless network that is upstairs, i cannot run a cable down here, however i've got 3 boxes that i want to run as servers..
1. Desktop running 10.10 (the one with the wireless card)
2. Server running 9.10 (no wireless card.. is currently connected through a wireless B gaming bridge)
3. An old P4 that I will be putting 9.10 on and running as a server.
Take the Desktop that has the working wireless card as my normal desktop and also running as a passthrough for the switch to go to the other two while still allowing all of the port forwarding to the other two to be handled by the router upstairs so basically what I want to do is this

Everything i've come across so far has been for going from a wired router to turn a box into a wireless AP unfortunately i need the reverse.. a wireless bridge. if someone can point me in the right direction (or i'm not against hand holding if it's available.
I first want to say that I am very new to Ubuntu so please forgive any ignorance I have successfully given internet access to my xbox by connecting it via crossover cable to my ubuntu 10.04 laptop and given the eth0 settings "share with other computers" My issue is that the ip address being given to the xbox is 10.42.43.10
How can I change this ip address given, or use a static ip address (ie 192.168.x.x) because using this ip address keeps my xbox from accessing windows shares on WORKGROUP on my 192.168.x.x network.
I am trying to configure an external wireless bridge for a few systems to replace a very long, duct taped cable.
I have it set up and it is connecting, at least I can see the pfsense router on the other side and ping any machine in the network.
Here's the issue, I cannot get dhcp to work across the link. I set a static address (dns servers and all) but when I try to ping google i get "Network is Unreachable"

My setup is above, I hope it comes out OK on this forum, and someone can understand what its supposed to be! My problem is I am not sure how to get [PC] to be able to see [Internet]. From [Laptop] I can get both networks to work, and have tried using brctl to bridge them, but as soon as I do "ifconfig br0 up" neither network... works anymore (cant ping either router).
I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.

Now I would like to install Debian in my main laptop, but I think it won't be able to connect to any wireless networks during setup and before installing firmware-brcm80211 and wireless-tools (its wireless card is a Broadcom 43224AG). That being, and to avoid connecting the computer directly to the router (it is not easy), I would like to bridge the EeePc's wireless connection to my laptop using a cable. I tried using the instructions found at the Debian Wiki, but I couldn't set it up properly.
I'm trying to bridge connections between a wired and a wireless connection in one of my computers. I was told it was impossible due to low-level limitations in the wireless subsystem, but apparently theres a way if you somehow forward packets from one port to the other. Is there a way I can achieve this?
View 1 Replies View RelatedMy current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).
So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.
I'm in the process of switching back to Fedora after years of hiatus, but I can't get my wireless card working. The card itself is an Atheros AR2413, and the problem is that it seems to appear OK in various places, BUT it doesn't detect any networks. I'm on Fedora 14.

Using Ubuntu Server 9.10 x64 and a tomato router to act as a wireless bridge to connect to another router. The reason I ask is because I do have the router set on WDS mode on the tomato firmware. I think I have it configured to the best of my ability, but when the interface is up, the signal doesn't get pushed out (no received packets) and it gives something at the bottom of an ifconfig eth0 "Interrupt:28".
