Port Triggering is a safer method for opening specific ports for special applications (e.g. video conferencing programs, interactive gaming, file transfer in chat programs, etc.) because they are dynamically triggered and not held open constantly or erroneously left open via the router administrator and exposed for potential hackers to discover. Port Triggering is a little more secure than port forwarding, because the incoming ports are not open all the time. They are only open when a program is actively using the trigger port.

There are no other pre-existing L2RP/IPSec port forward rules or otherwise conflicting port forward rules (e.g.: another rule for ports 500, 1701 or 4500) There was an L2TP port triggering rule enabled, that I toggled on and off with no change; Verified the firewall on VPN server had an exclusion for L2TP, or that the firewall is off. 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.
