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

[Tegger <xen@xxxxxxxxx>]

eth0, the real card, is online for connection to internet
so i need only a bridge between tap0 and eth1, the XEN Card.

so 192.168.100.x are used for real network and internal XEN network, but 
not for the connection to vpn.
So the virtual tap0 has 192.168.100.210-220
the eth1, XEN Card has 192.168.100.205
and Dom0 has 192.168.100.201

a Windows Domain has 192.168.100.19

and the rest is the real network....... i didn't understand how i must 
change the routings....
Openvpn Dom
