I have a Peplink Balance 20 that suddenly stopped responding to its web interface. It was at a remote location and the PEPVPN also wouldn’t connect. If I connected to it on the lan port, it would give me a dhcp address. I can ping it. But, a port scan revealed that all of the ports are closed. I have reset the router, and it defaulted to 192.168.1.1. It still gives me an IP address, but again, all the ports are closed. It was working properly for a number of years without any problems. Is there anything I can do to troubleshoot this problem further? Thanks in advance.
