after connecting your server per phoneline, peer to peer, not over internet,
you and your server are members of a network, so you can do anything,
what you can do, if your server is in your lan.
if your DNS doesn't translate the servername, take the ip-# ...

p.e. you can make a BDE-Alias ..,
or register this server in IBConsole, or the other IBAdmintools.

If you go over Internet (ISP), normally you have a lot of problems,
Firewall, that didn't support the IB-Service Port, etc. etc.
