We have 3 RV325 VPN routers at 3 different locations. The main router has 2 VPNs setup to the other 2 routers. We one router keeps restarting itself several times a day. This one has the 1 vpn tunnel going to the main router. We thought maybe it was an issue with the ISP modem, but they came and installed a new one & tested it by bypassing our network with no drops. I had an extra RV325 VPN router on hand so I restored it from an older backup of the router that was having the issue (was backed up with the latest firmware and zero issues). It too restarted itself. All 3 routers are on the latest firmware. All 3 routers have "remote login" disabled. I applied the recommended Deny policies for ports 443 and 60443 as recommended by cisco on all 3 routers. The router that is restarting is on a new APC Back UPS PRO BR 1000VA 10. I have replaced ethernet cables. I tried a new power plug for the router. Checked all switches, A/Ps & unplugged any ethernet cables not in use on the network. All PCs on the network (which is only 5) are running PCMATIC antivirus and are scanned every night. We have security cameras on our network with open ports and even tried keeping them disabled for a few days & it still did not help. We are ready to switch to a different brand of router because we have searched this problem online to find others having the same issues with their VPN routers. Here is a sample of our Log file...(ip addresses are X'd out)
