I'm starting thread for the first time so don't expect much of it.

I need advice on the following:

I want to make VPN connection from home (using dial-up) to server at work (using 256 kbps link).
At work I have w2k server with RRAS enabled (curently it is working as NAT for the rest of private range LAN), DHCP, no domain. Server is connected to ISP with some kind of wireless link with speed of 256 kbps). There is also software firewall with statefull inspection installed (Visnetic Deerfield Firewall).
At home I have w2k pro with 56k modem and same firewall.
Firewall can support only PTPP.

The question is: what ports (and for what address range) should I leave open on server at work and on computer at home?
the goal is that when I connect from home I have acces for shared folders, and maybie terminal service on server so I can admnister it from home.

Someone might say that I should search for previous posts, but when I type in VPN in search box there are over 400 threads, and I have much time for read them all.

Any kind of short advice, or reference to another post/thread or article is appriciated.

thank you
