Okay I am working backwards - haha - I know how to create a vpn server with windows 2000 or 2003 server with RAS. But I dont understand how people are creating a VPN with just windows XP Pro and a linksys router. I have 5 public IP's, I have a linksys wrt54g router and I have a dedicated XP pro machine. I think I have forwarded all the correct ports on the linksys router (which by the way I am not use to that, I am use to using NAT tables).
I guess my question is do I still use one of my external ip's with xp's vpn client software?
How does the linksys router know that external ip needs to go to a spfic internal ip with out nat?
I am guessing port forwarding.
I am confused on how this is set up? Give me a server, nat and some external ip's and I am good to go. But this has got me stumped. Can someone please explain what I am missing here.
