Forward these ports to the IP address that is assigned to the external interface of your VPN server. If you're routing traffic inbound and performing NAT at or behind the VPN server, then you must open your firewall rules to allow UDP ports 500 and 4500 inbound to the external IP address applied to the public interface on the VPN server. To enable VPN tunnels between individual host computers or entire networks that have a firewall between them, you must open the following ports: PPTP. To allow PPTP tunnel maintenance traffic, open TCP 1723. To allow PPTP tunneled data to pass through router, open Protocol ID 47. L2TP over IPSec. To allow Internet Key Exchange (IKE), open UDP 500.
