Nope, running Win 2000 Pro with ZoneAlarm. Doesn't work after closing Zone
Alarm either though. So I suppose the problem is sometihng to do with my
router's firewall settings. But other than that I'm having trouble working
it out. It seems that any computer outside of my house can access my server
OK, but if I try and connect to the server via the internet from inside my
LAN it doesnt work.
