VPN in SBS 2003

Hi Guys,

My name is Vikram I am working as Network and system Support Engineer. I have a question and hope u guys can help me with that.

My company wants that users can accress the company network from home and do work if they are off from the work . My present network setup is I am running windows 2003 SBS with exchange server and internet connection is provided by NTL (service provider) via broadband so my sbs 2003 server shares the internet connection with other users on the network. We are not useing ISa server because it gives us problem in shareing internet if ISA is running I dont know why.

I need to know how can I setup my SBS 2003 to support VPN and allow users to work from home. What setting do i need to change on server and what setting on clients. Do i need any new hardware

Please guys help me .... waiting for your quick reply

many thanks

Vikram
