Re: [Xen-users] Connecting dom0's with VPN?
If the connection between the two ending points (in the two facilities)
is ralized exlcusively by IEEE 802.1q VLAN capable switches all along
the path, then the obvious solution is to create a dedicated VLAN for
this purpose.
However, read this:
http://openvpn.net/index.php/documentation/miscellaneous/ethernet-bridging.html
This seems to be the stuff, needed for xen, but doesn't provide as
strong separation as the VLAN.
