Hi again.

I still have problems using NAT in xen.
I have the following set up:

brctl addbr testbr
ifconfig testbr netmask up

And I have a xen 3.0 domU, which has
vif = [ 'bridge=testbr' ]
ip = ""
netmask = ""

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:

1. dum0: netcat -l -p 1111
    dumU: netcat 1111
2. dumU: netcat -l -p 1111
    dum0: netcat 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 ?
