Oh I do have the router password, but I'm not allowed to install different firmware (which another question I'd asked awhile ago would've required). So yeah, port forwarding should be possible - not that I entirely understand what that means...

I do not have a shell account AFAIK; I do have a webpage which I can edit via MS FrontPage, but I do not know the appropriate server name to be able to access it in other programs and I've been told by IT that it's not possible to do - I don't believe this, but the old IT people claimed that and wouldn't tell me anything useful to help me do things otherwise. There are new IT people now though, so I keep meaning to ask again.
