Dear all, I'm do some experiment of vlan bridging with Linux Fedore core 3 with a 3com 3c905 NIC The config is as below: vlan 3 vlan 4 +-------+ eth0.3 |Linux | eth0.4 --------| |---- +-------+ and I would like to bridge b/w vlan 3 and 4 using the fc3 linux box. Gateway : 192.168.1.254 is located at vlan3 The 3c905 NIC is connected to a trunk port of a cisco 2950 switch. The command is used is : #modprobe 8021Q #vconfig add eth0 3 #vconfig add eth0 4 #brctl addbr br0 #brctl addif br0 eth0.3 #brctl addif br0 eth0.4 #ifconfig br0 192.168.1.1 netmask 255.255.255.0 up There's no error but the bridge doesn't work. Hosts in vlan 4 can't communicate with hosts in vlan 3 and vice vera. The bridge can't ping the default gw either. Can any one give adivse if this can be done or not ?? [PS: I have tried with 2 NICs and each connected to a vlan and the brdige work without any problem) Thanks a lot. Rgds. Peter
