What do you mean by that?  You have dialup/DSL service provided by your
school?  By ISP, I mean the provider of your networking service, not your
e-mail or web provider.  Your school could be your e-mail provider while you
have another ISP (Bell Sympatico, Rogers, etc.) providing the networking
service.

If your school really is your ISP, that's a configuration error on their end.
They should allow you to realy through them (and should also provide reversed
DNS service).

I doubt it.  Your router will be doing NAT so that outbound packets passing
through your router will be translated to appear to come from 199.212.73.21.
They don't know you're 192.168.0.100 and don't care.  This is a fairly
standard setup.
