Win2k Secure TCP/IP

Medium Priority

Last Modified: 2012-05-07
I have a couple of win2k machines that are on separate networks and separate domains.  I need a persistent and secure TCP/IP tunnel between the two.

What is the quickest, cheapest, and most reliable way to get that going.

I can not use hardware based VPN since one of the servers is not owned by us and can we can not place additional hardware there.

The connection needs to be established at boot up and needs to stay connected so that our TCP/IP application can communicate securely.

Our app is a simple socket to socket TCP/IP over a single port that is persistent.

thanks.

Thanks BillBach :
1) Sorry I forgot to mention.  My server is already running a Cisco VPN client on it, and you can't have to soft VPN clients running on the same server, as far as I know.

2) Our TCP listener is our own, by the remote TCP sender is not.

3) PCHelpware?  WHere does the encryption take place?

Ok, IPSec was easy enough to set up except IPSec does not play well with NAT.  It even does worse if you have NAT on both ends.

I ended up using Zebedee to create a VPN Tunnel.    It's free and works very well.

thanks
