I have a site-to-site VPN between two RV340 routers. The VPN connects and is functional for all purposes.
However, given time, generally the better part of a day, the service degrades. Users cannot access resource across the VPN. Ping does not work on either end. The VPN shows connected on both ends but for all intents is not usable.
I have aggressive mode set an one end. Logs are not very revealing as to what and why this occurs.
Thoughts? Any ideas and settings I should be trying? Thank you.
