We have two Peplink Balance 305 routers in High Availablity mode at our Datacenter. They have been working great for the about a year now.
They have been running firmware Version 8.0.0 build 2636
We host a business application via Web Services behind them.
This morning get calls due to downtime and when I check the servers web services are fine, but I am unable to even ping the IP’s for the services. No changes have been done to the router near the time of the issue and the last piece was to add port forwarding for a SSTP VPN on a server and removal of the local PPTP VPN.
We have a site-to-site VPN which during the issue works fine and allows me to connect to the routers.
A simple reboot of the master router resolved the issues and so I thought it best to update the router firmwares. Did the Slave first and then the Master with no issues.
8.0.2 build 2721
Got a call not 40 minutes later and see the same issue is happening again.
I see nothing in the event logs to guide to what is the issue
Again a reboot and it works again right away when the Slave takes over and continues after the master is back.
Need some assistance as I have nothing I can find to go on.
