Hardware :: WiFi Router Netcomm NB504 -Configuring For Bridge Mode?

Jan 4, 2010

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.

Debian :: Router Or Bridge Mode And Pppoeconf?

Sep 24, 2010

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.

Slackware :: Slow Dns Resolution With A Netcomm Router?

Jul 26, 2010

i have a nb5plus4w modem/router at home which acts as a dhcp server on my lan. upon connection it instructs the clients to use 192.168.1.1 as a dns server (which is the ip address of the router) and linux machines are happy to use that in /etc/resolv.conf. now the issue is that under these conditions dns resolution is sloooow. there have been some discussions on the net saying that the router is not a 'real' dns server (don't know what that means), but the only way i have been able to get around the issue is to edit /etc/resolv.conf to use my isp's dns servers and then chattr -i the file so that dhcpcd doesn't change it.

this approach works for the desktop and even though it is ugly it's effective. the laptop is a different issue. if i take it out of the house i have to chattr -i and let the new network put it's dns addresses in and then change it all back when i get home so, the question is... can i do something to stop doing chattr and get the dns performance of a windows machine (dns resolution is quick on the windows machines)?

Ubuntu Networking :: TP-Link Wifi USB Adapter: Cannot Setup It In Master Mode To Use PC As A Router

Jun 10, 2010

I got two issues with my wifi usb adapter:

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:

Code:
Ubuntu 10.04
Linux 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux

Networking :: Configuring Ethernet Bridge?

Nov 3, 2010

I am using 3 machines in a LAN connected through a hub. My intention is to have a end-to-end connection between 2 machines so that I can control delay/loss rate. For that purpose, I am using a 3rd machine with 2 NIC and intend to use a bridge and installing Dummynet in this machine to control the traffic between the other 2 machines.I have successfully installed Dummynet in the bridge machine. Now I require to configure Ethernet bridge in the machine. What is the process? Do I need a kernel compilation or can be done without it? read somewhere that recent kernels can be configured without recompilation.I am using Mandriva 2010 with 2.6.31.5-desktop-1mnb kernel.

Networking :: Configuring Xen Bridge (2 VM Inside) Under Same Subnet

Apr 28, 2010

I have installed a Xen with 2 VM's inside. They are all under the same subnet. The Xen machine can see the outside network but both machines in it cannot.
How do I create the bridge correctly (to xenbr0 i guess) so it fixes this?

Here's what I tried: It's RHEL5.3
1. '/etc/sysconfig/network-scripts/ifcfg-eth0' is ok on both VM's
2. iptables service is disabled, system-config-network shows IP,DNS, GW are correct.
3. On the VM's the route -n shows the gw ip though I cannot ping it.
4. checked hosts.allow, hosts.
5. In '/etc/xen/xend-config.sxp' unmarked:
(network-script network-bridge)
(vif-script vif-bridge)
6. in xen/<images_location>/ I modified vm.cfg so vif = [ 'ip=10.2.0.54' ] for one of my virtual machines.
7. I cannot however find '/etc/network/interfaces', can anyone advise if actually in my case it's the ifcfg-eth0?
8. I basically followed the Bridged Networking scenario in Xen Networking: [URL]

Ifconfig on the Xen Parent:
[root@XEN_PARENT]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:50:56:8B:3A:E4
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

Networking :: Transparent Router / Bridge - Ppp Interface

Jul 27, 2010

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.

Ubuntu Networking :: Using Tomato Router As Wireless Bridge

Feb 5, 2010

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".

Debian :: Switch The Kvm Network Using Bridge Mode?

Dec 20, 2008

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

Code:

allow-hotplug br0
iface br0 inet dhcp
bridge_ports wlan0
bridge_fd 9

[code]....

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)?

Ubuntu Networking :: OpenVPN Bridge Mode Firewall?

Nov 7, 2010

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.

OpenSUSE Network :: Adsl Modem Acting As A Bridge To My Router Setup - Connection - Internet Went Slow ?

Jun 19, 2011

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 !

Software :: Installing/Configuring A Proxy Server On A Linksys Router?

Mar 18, 2009

I have been happily running the (always latest) version of PolarCloud's Tomato software on my LinkSys WRT54G for about 2 years now. I am looking for a way to setup a Proxy Server on my Tomato-based router to use from a remote machine somewhere in the web cloud.The reason for wanting to set this up follows. I normally run Squid on a Ubuntu 8.04 box, which I use while I am away from my LAN at home to browse the net (I like to keep things between me and my ISP, as much as possible . I rely on my proxy server on a daily basis. The way it works is I SSH into my Ubuntu box, and forward squid ports. I then point my browser to the proxy on my box. For various reason, however, I would like to set it up so that I can also do this via my router. So, I would like to be able to ssh to my router (I can already do this), forward the proxy ports, and surf the nets happily via my router at home. I am happy to use existing solutions (if possible), such as privoxy or squid, and am also open to setting up a custom-based solution, as may be necessary.

General :: Configuring WPA WiFi In Ubuntu 10.10?

Jan 8, 2011

I am trying to configure my wireless network on my laptop running Ubuntu 10.10 and am having a bit of difficulty. I am a complete Linux newb, but want to learn it, hence the reason I'm trying to set this up. Here's the vitals:It is a Gateway 600 YG2 laptop. It was previously running Windows XP, but I installed Ubuntu 10.10 in place of it (not a dual boot, I removed XP altogether).I have an old wireless card that I'm trying to resurrect. I haven't really used the card in a couple years, but it seems to still work, I just can't connect to my home's wireless network. The card is a Linksys WPC11 v2.5. When I plug it in, Ubuntu recognizes the network, but won't connect to it. My home network uses WPA encryption and the only connection type that Ubuntu's network manager is giving me is WEP and then it asks for a key -- I have no idea what that key should be.

So, basically, I'm asking, is there a way I can instead connect through WPA? I've tried creating a new connection in network manager, but that won't work, it keeps falling back to the WEP connection and asking me for a key. I have tried to install the XP driver using ndiswrapper but I don't know if that's working or not. Is there a way to tell if:A) the card is working as it shouldB) the correct drivers are installed (again, I installed the XP one using ndiswrapper NET8180.INF, but I'm not sure what to do next)
