Windows 2000 WIFI VPN

[cconk01]

Hi, I am new to this forum, but i have been having trouble with windows 2000 server. Currently i have 2 Servers. Server A runs DHCP, DNS, AD, File Sharing, and internal web site. Its Ip is 10.0.4.1. Server B is just a pretty standard computer, pentium 3 1.3 ghz running windows 2000 server, with two networking cards, card 1 is: 10.0.4.2 and card 2 is: 10.0.4.3. Card 1 connects to the switch behind the firewall, while Card 2 connects to a switch connected to three WAP's.

My question is: i want to secure my wireless clients though a VPN. I have been able to have clients connect to Server b, but they arent able to acces the Internet, other computers over My Network Places, and the file server.

What should i do? i am new to the IT area, but i know a decient amount. Any help would be great. Also i have included a diagram that i created that should be somewhat helpfull if this was confusing. Thanks!
