Windows 7 VPN computer-to-computer
This allows a connection from the COMPUTER1 to the COMPUTER2 computers.
Additional configurations
Router Port Forwarding
On the Linksys router, I setup port forwarding for TCP/UDP traffic on port 1723 to forward to theĀ COMPUTER2 computer.
Firewall
On the COMPUTER2 computer, I setup a firewall rule to allow INCOMING traffic on port 1723. I made it specific by allowing only my user account to do this.
Antivirus
Some people report issues with their antivirus and/or internet security software blocking traffic. Avast seems to be ok.
