[gdm-list] When gdm3 server connects to vpn, i can't connect to the server

[王东举 <shuwei1204 163 com>]

Hi

    my server use debian 6.0.5 gdm3 2.30.5.
    I changed the deamon.conf in /etc/gdm3/ as following:

#########################    
[xdmcp]
Enable=true
Port=177
########################

i can connect my server normally.

But when i connect the vpn(use xl2tp) on the server,
I can't connect to my server via xmanager.

I changed the route table, but it does nothing.

Anyone know it?
