I wonder what is your opinion about the best method for using an ADSL modem. Router or bridge? I did read some articles that say "that the bridge mode gives you more stability and has higher speed". Is that true?
Furthermore, you suggest any alternative to "pppoeconf"? I've been getting this errors ( in the plog), related to "PAD packet loss" and also errors in "PPPOE Discovery", even when I am connected. When this things starts to show up on the log, my connection "pauses" for some seconds. I do not feel very safe with this program.
I'm interested in configuring two Netcomm NB504 WiFi routers to work in a Bridge configuration. ie. Local PCs ---> Router <----//----> Router <--- local PCs
The NB504 router doesn't appear to have a native "bridge" mode. However, it does run Linux according to the documentation. I'm interested to hear from anyone who has actually got two of these routers to work in a bridge configuration. I'm not interested in general theoretical comments - only solid advice. I am also not interested in using other hardware for this exercise - I have two of these devices available for use in this project.
I've successfully install kvm with private network (nat) up running. I want to switch the kvm network using bridge mode (or host-interface), but do not success. env: nic iwl4965/ kernel 2.6.27.8/ debian etch upgrade to lenny/ kvm 0.9.1/ hardware hp 6910p The doc I follow up is at [URL] The way how i set it up is to modify /etc/network/interfaces by adding following section to enable br0
However, the problem is the guest os, which starts with -hda k1.img, can not access to the internet. Is there any step I miss? or it is because wireless does not support bridge (I've heard doc says that wireless does not support wireless bridge)?
I'm trying to setup openVPN on debian, well this worked. But every client will get the same ip (172.17.0.6 - local it is). how to set my server in bridge mode. I've read about: server-bridge LOCALIP 255.255.0.0 172.17.1.20 172.17.1.100
BUT, my server has no ipv4 address, but only ipv6: 2001:41d0:2:b2d6::542a:74a so I am not sure how I can do this.
The 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.
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".
I had an intstall of 10.2 that I'd been using forever that has a Prisim card in it that I was using as router/access point across a bridge. Recently I rebuilt my machine (replacing a bunch of drives) and installed 13.1. I'm having some difficulty getting my AP reestablished. The card is showing on the pci bus
I have installed CentOs 5.4 for Snort sensor , on the location where i intend to place the Snort sensor to listen for internal firewall leg (LAN) the switch doesn't support port mirror so i would like to create with 2 nic's bridge and pass trough the firewall internal leg my question how do i set such configuration.
I have OpenVPN running on my Ubuntu Server just fine. I can connect over the Internet and access all my resources on the LAN via bridged mode perfectly. My server only has one LAN card and sits behind my router, which means it has a private IP address of 10.1.1.2....Which brings me to my question. I want to open up access to my friends via OpenVPN, but I don't want them to be able to access other machines on my LAN (e.g. 10.1.1.20). However, I do want them to be able to talk to each other and pass broadcasts (old LAN games), as well as my laptop (let's say 10.1.1.7).I've tried using iptables to block traffic to the LAN (such as .20), to no avail. I've been reading up and it seems as though iptables won't even filter the traffic, as it's passed at a lower layer. Is this true? If so, what do you recommend I do in order to prevent my buddies from accessing the rest of my LAN while siumultaneously allowing broadcasts pass for some very old Windows LAN games (we're talking Windows 9.
my both linux and windows has 2 network cards each.
basicaly it is vLan cards, each server has 2 network cards. one to main switch and one to local IP.
data will be going like below:
internet ----------------> eth0 --> linux --> eth1 ----------------> Windows.
i have vLans on both servers. And i need cross connection setup. And use linux in bridg mode / cross connection .
actualy i want to use Iptable rules to filter bad packets and forward good packets to windows. i have scripts how to forward packets to windows. but the problem is i dont know how to setup both servers in this topology. and how to make linux as bridge.
All it should be in transparent mode. Not in NAT mode.
I configured squid in transperant proxy and it's working fine.Now i tried it in bridge mode for that i did setup for bridge mode and it's working fine.But i can not get any http request in squid access log.i can see traffic from my bridge. tcpdump -i br0
I have 2 wlan cards. wlan0 and wlan1. wlan0 is in AP mode(Master mode) using hostap. wlan1 is connected to another wireless network and is in Managed mode. Now I want to make a bridge between wlan0 and wlan1. I do it like that:
How would I configure my box to connect to a modem in bridge mode?
I have a server at home that im migrating over to be the default-gateway/router. I have everything else setup (dns,dhcp etc) now just need the ppoe part, or so i beleive?
I have two interfaces. eth0 (lan) and eth1 ready to connect to the modem. The modem is in bridge mode ready to go. What is my next step? Are there any good guides, I didn't find any.
i am using debian lenny stable and gnome desktop environment and having an i386 architecture.I configured to connect to the broadband connection using pppoeconf with the default options and the setup went smooth.when i connect to the internet using the command
and when i check that if i am really connected to the internet i used the following commandjj@debian#ifconig
it showed my ip address dns,etc in the ppp0 coloumn .But when i open up my iceweasel browser and also the epiphany browser and when i try to load a web page it states that it couldn't find the server.so guys please tell me how to configure it correctly and please tell me what i did wrong. p.s when i tried to configure the adsl connection by the alternative using the command pppoe-setup it states that It couldn't find the /etc/ppp/pppoe.conf file so do i have to create it on my own?
any one are implementing Transparent Cache in bridge mode. after googling i found article but its not working for me. any one have done this before ? [URL]
I have got the following Problem: I installed the 64 bit lxde Debian version... I couldnt configure the network during the installation because I just have a dsl modem and not a router... so the configuration of the network failed.... after the installation I started debian... and was surprised about the lack of "basic system configuration"-software that had been installed... I couldnt find aptitude or whats the debian-Update-Programm called .... instead I found OpenOffice... HAE? then I tried to configure internet access..... so I started a terminal and tried to start pppoeconf... but the program wasnt found! ARRRGG! What am I doing wrong here.... Why are these system utilities like pppoeconf not always installed...
I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !
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.

I use to have problems getting my wireless card to connect to any network on ubuntu. I discovered that I needed to change my encryption mode from Auto to AES or TKIP on my router. After I did this I was able to connect to my network with full wireless n support. I am using a d-link DIR-615 wireless n router.So far I know this works perfectly on 9.04-10.10 alpha.
1) it cannot see any networks around 2) i cannot setup it in master mode to use my PC as a router
As far as i can see, the device is recognized and the correct driver (rt73usb) is loaded. I was able to connect to a laptop somehow (the laptop could see other networks and the adapter's PC-to-PC network). I'd like to make it work as a router, i.e. share my internet connection (eth0) via wlan0. Here is what i have:

there was a missing line in /etc/network/interfaces:Code: Select allauto br0
I have two ethernet NIC's on my debian server. One built-in Realtek [eth0] (attached to internet), and a PCI Nvidia ethernet card [eth1] (attached to my Win7 netbook). I used this guide to setup the bridge: url. It worked when I was behind a router. But when I moved the computer in front of the router, to direct connect to the internet, the internet stopped functioning on any device that I plug into my Nvidia NIC. The name of my bridge is 'br0'. Does anyone know how to fix it, so I can route the internet to my second NIC?
My Win7 netbook displays this at an 'ipconfig' command: Windows IP Configuration
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo br0 iface lo inet loopback # Set up interfaces manually, avoiding conflicts with, e.g., network manager iface eth0 inet manual iface eth1 inet manual # Bridge setup iface br0 inet dhcp bridge_ports eth0 eth1
I am a (somewhat) newbie to Linux (but have an extensive Windows background), and I have just installed Debian Squeeze in an old EeePc 701 4G using the netinst version only with the following packages:
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 have a debian squeeze box with dual NICs that I'm trying to configure with two virtual hosts. I'd like to have one of these machines act as a router for the 2nd NIC so I can plug in a switch and have a separate subnet.
Something like: - Openwrt router 192.168.1.1 (firewall/vpn/stats for 192.168.1.0/24 domain) - KVM machine with 2 NICs (192.168.1.2) - Virtual machine #1 has a fixed IP of 192.168.1.3 (virtual nic) - Virtual machine #2 has a fixed IP of 192.168.1.4 (virtual nic) but also controls the 2nd nic and routes 192.168.80.0/24
I'd like to use the 192.168.80.0/24 network for testing equipment without poisoning my existing network.
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?
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.
I recently installed Lucid 10.04 on a P-IV desktop. The install went extremely smooth and Ubuntu was up and running. Hats off to the Ubuntu folks for the excellent user-friendly experience in the installation process. However , I have run into a networking issue. I connected my PC to the router issued by my ISP. This is a plug-n-play type of connection where the username/password settings are stored in the router and there is no configuration required in Ubuntu for accessing the internet. All I need to do is connect the router and my PC using the LAN cable. I was able to surf the net without any issues.
A few days later , this ISP service was down and hence I switched to another wired ISP. This ISP required me to dial a connection using another supplied router. I setup the connection using pppoeconf where I was asked to enter username/password. Again I was able to surf the internet without any issues. Next , I shutdown the system and before booting it , I switch back to my original ISP connection (the plug-n-play one). But now I am not able to connect to the internet. The router lights show that my PC is connected to it , but when I issue ping 192.168.1.1 to check connectivity with the router configuration, I get
Code: $ ping 192.168.1.1 connect : Network is unreachable. Also , issuing ifconfig does not show eth0. NM-applet also does not appear in my notification panel at the top. How I can go back to using my original plug-n-play ISP connection? I have read some posts about networking issues , but none quite like this one. Please note that all my Internet connections are Wired connections.
Here is my interfaces file Code: $ cat /etc/network/interfaces auto lo iface lo inet loopback iface dsl-provider inet ppp pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf provider dsl-provider auto eth0 iface eth0 inet manual
I am a Ubuntu user (10.04 as of now), since I use it, over a year, I have to manually enter the command $ sudo pppoeconf everytime I turn on the computer and want to connect to the internet, the I click enter some times, enter my password of my internet provider, then I click enter some more times to have internet.I have to do this boring work, 3 times a day, just now I am asking you if you know any way of automatizing this?
