Re: [Xen-users] Domain with openvpn-server-bridge to Dom0-bridge problem

If I'm reading your information correctly, the bridge (br0) of your
Openvpn domain only connects to eth1 (XEN-Dom0) and to tap0 (Openvpn's
virtual interface), but not to eth0 (pass-through real nic). If that was
true, your problem lies there.

Another point could be, that your routes are messed up. You seem to be
using 192.168.100.x as the real external network *and* the internal XEN
network. But by assigning two ip addresses to eth0 and eth1 in Openvpn
domain, you get two routes for, leaving the choice to
the operating system. There should be only one address assigned to the
bridge, I think.

I hope one of those points helps you.
