Hi again. I still have problems using NAT in xen. I have the following set up: brctl addbr testbr ifconfig testbr 10.59.61.1 netmask 255.255.255.0 up And I have a xen 3.0 domU, which has vif = [ ''bridge=testbr'' ] ip = "10.59.61.2" netmask = "255.255.255.0" When the domU is up, I can ping it from dum0. And I can ping the dom0 from the dumU. And I can create a netcat connection: Running 1. dum0: netcat -l -p 1111 dumU: netcat 10.59.61.1 1111 2. dumU: netcat -l -p 1111 dum0: netcat 10.59.61.2 1111 I always get a connection. However characters typed in dum0 appear in domU, but never the other way around. I already tried ethtools -K eth0 tx off but I didn''t help. Anyone any guess ?
