strange question about VPN Server

Post by chen4u » Thu Aug 04, 2022 8:12 am

Hello, everyone
I have installed softether VPN to build a local area network, but it is strange to find that the server cannot be connected after a period of time. The symptom is that you cannot find the virtual HUB on the client side, and the dynamic domain name of the server cannot be pinged from the client. However, the dynamic domain name resolution is normal. I tried to install a client on the server and the connection is normal. The virtual HUB is also easy to find. What is the fault and how to deal with it? I thought it was a problem caused by the firewall on the server, but I installed the firewall and turned it off to no avail, please give pointers to the experts, thank you!

thank you all

Pinging WAN destinations is inconclusive. On the server side's router enable IP forwarding to SE port, then in a client's browser enter this diagnostic test address: https://vpn-ddns-addr:se-port/
