Hi,
I think you might want to check this:
Here is ifconfig from dom0:
eth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF

Especially the hardware address.

Hi,
Thanks for the reply. That is the hardware address that was setup
when I installed Debian. If I try to change that hardware address in
/etc/network/interface config file I can't ssh to my dom0 machine
anymore from other computers in my network. I know it looks weird but
if I change it my network on eth0 dies. Now I changed my
configuration a bit and it looks like this now:
This is my network script at the moment, found this one from this list:
#!/bin/sh
brctl addbr xenbr0
brctl setfd xenbr0 0
brctl sethello xenbr0 0
brctl stp xenbr0 off
ifconfig eth2 0.0.0.0 down
ifconfig eth2 0.0.0.0 up
brctl addif xenbr0 eth2
ifconfig xenbr0 10.0.0.1 netmask 255.255.255.0
sleep 5
brctl addbr xenbr1
brctl setfd xenbr1 0
brctl sethello xenbr1 0
brctl stp xenbr1 off
ifconfig eth3 0.0.0.0 down
ifconfig eth3 0.0.0.0 up
brctl addif xenbr1 eth3
ifconfig xenbr1 10.0.1.2 netmask 255.255.255.0
sleep 5
ifconfig eth2 0.0.0.0
ifconfig eth3 0.0.0.0
exit 0

and kernel routing table on dom0:

Now I can ping my dom0 from domU's but everything else is still
failing. Can't ping my domU's from dom0 and ssh doesn't work at all.
So there is little progress because ping wasn't working at all before
and now it works from domU to dom0.

Could you provide me with the output of 'brctl show' ?
Thanks!
Hi,
This is a bit strange. I changed my hardware address in
/etc/network/interfaces file and booted my computer. Now I can access my
dom0 from my domU with ssh but now I can't access my dom0 from other
computers in my network like I used to before changing that hardware
address. But here is the output you asked:
bridge name bridge id STP enabled interfaces
xenbr0 8000.001cf05b69f8 no eth2
vif1.0
xenbr1 8000.001cf05a5d72 no eth3
vif2.0
