Hi,
when you setup some devices with an VPN Tunnel and the Peplink-Hardware is behind a Firewall or an Router from the ISP you have to use your Computer with Telnet to check if e.g. TCP 32015 is openend.
When you have to fix a problem from a remote side this could be a Problem.
I would be happy if a Port-Tester would be added to the Tools like Ping and Traceroute.
Regards
Dennis
