Greetings, Thanks for the information. Unfortunately, there wasn't any VLAN specific information here. After some testing I got it to work. I had to create a bridge device for each VLAN like so:
ifconfig eth1 0.0.0.0 promisc up ifconfig eth1.100 0.0.0.0 promisc up ifconfig eth1.400 0.0.0.0 promisc up ifconfig eth1.800 0.0.0.0 promisc up ifconfig eth1.900 0.0.0.0 promisc up brctl addbr uml-bridge0 brctl setfd uml-bridge0 0 brctl sethello uml-bridge0 0 brctl stp uml-bridge0 off brctl addbr uml-bridge1 brctl setfd uml-bridge1 0 brctl sethello uml-bridge1 0 brctl stp uml-bridge1 off brctl addbr uml-bridge2 brctl setfd uml-bridge2 0 brctl sethello uml-bridge2 0 brctl stp uml-bridge2 off brctl addbr uml-bridge3 brctl setfd uml-bridge3 0 brctl sethello uml-bridge3 0 brctl stp uml-bridge3 off ifconfig uml-bridge0 1.2.3.4 netmask 255.255.255.0 up ifconfig uml-bridge1 2.3.4.5 netmask 255.255.255.0 up ifconfig uml-bridge2 3.4.5.6 netmask 255.255.255.0 up ifconfig uml-bridge3 4.5.6.7 netmask 255.255.255.0 up brctl addif uml-bridge0 eth1.400 brctl addif uml-bridge1 eth1.100 brctl addif uml-bridge2 eth1.800 brctl addif uml-bridge3 eth1.900 tunctl -u uml -t uml-conn0 brctl addif uml-bridge0 uml-conn0 tunctl -u uml -t uml-conn1 brctl addif uml-bridge1 uml-conn1 tunctl -u uml -t uml-conn2 brctl addif uml-bridge2 uml-conn2 tunctl -u uml -t uml-conn3 brctl addif uml-bridge3 uml-conn3 ifconfig uml-conn0 0.0.0.0 promisc up ifconfig uml-conn1 0.0.0.0 promisc up ifconfig uml-conn2 0.0.0.0 promisc up ifconfig uml-conn3 0.0.0.0 promisc up Then I had to start the kernel like so: su uml -c /usr/src/linux-2.6.23.1-um/linux ubd0=debian-root ubd1=debian-swap eth0=tuntap,uml-conn0 eth1=tuntap,uml-conn1 eth2=tuntap,uml-conn2 eth3=tuntap,uml-conn3 mem=256m con0=fd:0,fd:1 con=pts Thanks, Jason > -----Original Message----- > From: Jonas Meyer [mailto:[EMAIL PROTECTED] > Sent: Friday, November 23, 2007 5:19 PM > To: Jason Gauthier > Cc: user-mode-linux-user@lists.sourceforge.net > Subject: Re: [uml-user] Networking and VLANs > > I would recommend you use tun/tap.
