Hi,
if you want to make a virtual connection between 2 machines over the internet, then your are at the right place.!
Firstly(of manny mre thing to come..),
you need to make(/Configure) one machine a server and another a client for this..i mean for VPN to work. So, you could decide which machine XP/98 to be made as a server. I would prefer XP, not just becoz it is the latest..but I hate 98 totally..and Microsoft has made 98 tailored just for home users...i dont expect good things fomr it..(did I say I have 98 as my PC!)
Then you need to make(/Configure) the other machine as the client. If you choose to make 98 as the client..you have a VPN client readily available from Microsoft to use..! and it is FREEEEEE!..
Now lets come to the more interesting aspect of this situation.. What are the possible bottlenecks you might run into..?
You could configure your XP machien as a VPN (RAS) server.
This you culd configure as PPTP (Microsoft way..) or L2TP/IPSec (IETF standard..and ..truly an industry standard..as it ensures mroe security and authenticity thru encryption).
Now after deicding which way, then you follow the required steps (widely available over the internet) you are ALMOST ready..
Finally, you might want to check the issue of NAT coming into your scenario. If the 2 machines are behind NAT bozex which do PAT..then you might have some prolems with L2TP/IPsec. You mgiht want to check withyour ISP for making IPSec traffic go thRU..
so if you do this..lets know how was yoru exprience..I am
sure there are a lot of people who culd benefit ..
goodluck
Vishu.
