Remote use of XDMCP

[Ansar Mohammed]

I didn't say tunnel XDMCP, I said tunnel X through ssh. 

Also, even though you are using VPN you have to tell xdmcp which IP address
to use (and send in the packet datasream) as the source. You typically
experience the problem you are having if you are multihomed (as a VPN client
technically is) and your X Client is not using the IP Address used by your
VPN interface.
