Sounds like they might be using MS Proxy Server. If you check in Internet
Explorer\Netscape Navigator for Proxy settings that should tell you
(likewise checking your IP address can help but it is possible to use
Internet valid IP's inside a firewall, just bad practice) if there's proxy.
You'd have to check the NT server to see if it's MS Proxy.

If they've got a MS Proxy (or another proxy?) you should be able to set up
Reverse Proxying. You can either:
1) Assign another valid external IP to the NT box and reverse proxy it to
your internal address
2) Use another port on the existing IP (I think you can do this)

If you use 2 then the web server will be existinghost.domain.com:81 or
something (i.e. you'll need to use a port, but should be fine at least for
testing.

Actually I know very little about the configuration of the LAN using in the
office, I'm just a consultant doing a project for them and the network
administrator is not too willing to modify too much just for my project, or
not even want to tell me as an outsider too much about their configuration.

Anyway, in my project I have another web server on the LAN running in
parallel with the main NT server, there is a home page in my server which I
want to be accessible from outside the building. Right now I can go up the
internet from my machine, but couldn't call in from outside even the web
server program is accessible from another machine within the same building.
But I know the LAN is well protected by a proxy server since it has over a
hundred workstations connected to it.
