remote connections to xdm

[James D. Parra]

Hello,

I set up xdm on a server (FreeBSD 9)and I can connect to it from any machine on the same local network as the server, but not from computers on different network, for example networks connected via a tunnel. Is there something to be added in /etc/hosts.allow or in the xdm config files to allow connections from specific IP subnets?

Thank you in advance.

James
