Direct TCP/IP through PPP to SLiRP?

I teach at a middle school that has been having problems with Internet lag (as well as DNS and Proxy glitches).  We share a T1 line out.

At home, I dial from my Mac running FreePPP & TCP/IP into a UNIX machine running SLiRP to emulate my PPP connection.

Is it possible to use some PPP connection software and make a direct connection to the server running SLiRP (not the same domain) much as I do dialing in at home?  That is, talk not through the router at my school but to this other machine and invoke SLiRP instead?

I would then use the same MacTCP (or TCP/IP) settings as home, but instead of executing a dialin script I would need to connect directly with a script to invoke SLiRP on the UNIX end.

PPP and SLIP (whatever version) are both strictly dial-in options over POTS (Plain old telephone service)- an analog connection. On a network, you cannot use either of these. TCP/IP via MacTCP or TCP/IP settings is the way to handle routing on a network. If you are on a network, and there is a router between you and the Unix box, the only way to get to the Unix box is through the router. The router in this case is referred to as a gateway. If you wanted to connect to the Unix box via the same method you use from home, you would need to dial in from the machine at work.
