I have a Peplink 300 that has been in use for several years. One week ago email stopped flowing through the Peplink 300 and I could not VPN through the Peplink router. I rebooted the Peplink 300 router and email started working but I still could not VPN from home to work. Once at work, I unplugged the Peplink 300 router, waited about 2 minutes and plugged it back in. After powering off / powering on I was able to VPN from home to work.
The symptoms alone make me think of some corruption going on, but then when I went into the admin screens and tried to look at Network / Firewall the web page came up but was blank with three spinning icons showing.
What to do? I don’t want to have to start over with the configuration, there have been many changes in the last five years or so and redoing all of them will be difficult. Looking for the best procedures with the best possible outcome.
