joepalm,
Most routers support PPTP VPN's. They use built-in PPTP VPN through Windows. This will allow you to get to Exchange with Outlook 2K in workgroup mode AND access all your file servers, etc. just like you were at home. Just slower, of course.
I use the Netopia R9100. Works great. Linksys has some routers that will support PPTP as well.
