I have Peplink Balance 380 firewalls at two locations. I use the built-in PTPP server on each to provide VPN access to each location. They’re both the same hardware revision (5) running the same current firmware (5.3.9 build 1676).
VPN access works properly at both locations. However, at only one location, PTPP connections always disconnect after exactly one hour. This happens regardless of whether or not that PTPP connection is active or idle.
How do I eliminate this one-hour timeout?
