Hi I have been using Shorewall for a while now and find it very useful and easy to configure, I am learning iptables and having trouble getting the bridge to successfully work with squid, although I get it working with Shorewall straight away? Does anyone know the rules to successfully use squid with a transparent bridge? Internet – router - (bridge eth0 – eth1) – local lan auto lo iface lo

Hi, I had successfully setup my bridge (br0) but after few minutes the br0 interface seems not working. ifconfig eth0 0.0.0.0 ifconfig eth5 0.0.0.0 brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth5 brctl stp br0 on I check on my system's /var/log/syslog file. It shows something strange messages as below: - Jan 2 10:44:22 fw01 kernel: ipt_tcpmss_target: bad length (64 bytes)

Hi there, I'm currently experiencing a minor problem using the bridge module under kernel 2.4.27 part of the Devil Linux distribution (http://www.devil-linux.org). The problem I am having is that when the bridge is unloaded during a reboot I receive the following errors in /var/log/messages: Nov 14 13:22:13 src@Devil kernel: unregister_netdevice: waiting for br0 to become free. Usage count =

Hello, I how an embedded processor that needs to act as a bridge between a wireless and wired network. I have managed to bring up the bridge fine. I can also bring up the bridge with a static ip address. However I can not figure out how to bring up the bridge with a dynamic ip address. Is it possible to for a bridge to get a dynamically assigned ip address? Oliver

re can somebody tell me what am I doing wrong (at this late night hour), because vlan are not getting bridged at all. ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 ifconfig br0 up vconfig add br0 X vconfig add br0 Y X = vlan-ID (example: 222) Y = vlan ID (example: 223) # brctl show bridge name bridge

Santiago, I appreciate your offer. I'm not really a kernel hacker, however I do know C and I would be willing to try if you point me in the right direction. Here is my first attempt using Debian running on an UltraSPARC: debian{root}:/root<512>strace -f -F -v brctl addbr br0 execve("/usr/sbin/brctl", ["brctl", "addbr", "br0"], [/* 16 vars */]) =

I''m converting my network from a "one interface per segment" to a "single connection with vlans", well, some hardware I have requires using different vlan IDs. suffice it to say I need bridges to connect a few different vlans that should all be one but can''t be because of firmware constraints. so my first step is to get shorewall to know about bridges.

I'm sorry to bother you but I'm stuck I can not make a bridge work for me. My current configuration is: eth0 Link encap:Ethernet Hardware Adresse 00:1d:7d:d1:06:bd inet Adresse:192.168.1.1 Bcast:192.168.1.255 Maske:255.255.255.0 inet6-Adresse: fe80::21d:7dff:fed1:6bd/64 G?ltigkeitsbereich:V according to all what I could find in the net.

Hi All, I''m trying to do some traffic shaping on an ethernet bridge. Currently, I have the following setup working: ifconfig eth0 down brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 brctl stp br0 off ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up ifconfig br0 up This creates a bridge consisting of eth0 and eth1. So far so good. I now want to use tc to shape traffic

I'm trying to bridge a wired network and a wireless network, but I'm having some trouble. No traffic seems to be passing through the bridge. When I issue a "showmacs" command to brctl, I am able to see MAC addresses from both networks. I am also able to ping both networks from the bridge machine. When I issue a "showstp" command to brctl, the wireless access

Hi! I have an bridge that keeps crashing (random times .. days with 5-6 crashes with normal functioning of 1-2 weeks) my machine that is used also as gateway (nat). the problem is that i don't have an log of the kenel panic so i don have what to post ... The configuration of bridge is like this: (each eth0 and eth1 are in different vlans in switch) $IFCONFIG eth0 0.0.0.0 $IFCONFIG eth1

I've got a 2.6.8 kernel with bridging enabled as a module, two nics (LNE100TX and RTL8139) and i've run the following commands with no errors modprobe -v bridge brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 both interfaces have 0.0.0.0 as their addresses and brctl showmacs br0 shows the macs for both internal cards. However, bridging doesn't seem to be working at all.

Hello, I connected the network 192.168.1.0 with 192.168.2.0 over the internet trough a GRE-Tunnel. I don''t know if I set up all things right: The client-pcs in both networks have a subnet mask of 255.255.255.0 and 192.168.2.x''s default gateway is the server wich has started the tunnel. The 192.168.1.x''s default gateway is 192.168.1.250 wich routes traffic destinated to

Hello, I thinking about using PCI passthrough to dedicated a domU as firewall. I understand PCI passthrough concept. When done, my domU will see network card and the dom0 won''t any more. So I''ll be able to filter all trafic from outside, since it will go through network domU. Then, how will I be able to connect other domU (and maybe dom0) to the network domU ? In a normal way,

Anyhow, I ran into it when setting up this strange network of mine.. I dont think my setup is causing anything strange however..

I've been playing around with qemu and wanted to make the guest OS instance visible on my network. This meant getting bridging and tun/tap working. After getting things working by pasting command from the CentOS wiki article plus adding a few enhancements, I decided to capture the process in a shell script that would be suitable for a user in the sudoers file to fire off. Not sure why

Dear Centos-Virt: This is actually a second request for help on the same issue. I finally got to try what several months ago was replayed to me and no joy was to be had. I am afraid the original thread got stale and also had extra, unnecessary data in it. Guest=XP Pro, SP2 Host=CentOS5; # uname -r; 2.6.18-8.1.15.el5 VirtualBox-1.5.0_24069_rhel5-2.i586.rpm
