Linux softether client acting really strange

Post by novembre » Sat Jul 18, 2020 11:39 am

Hello, i am trying to connect linux softether client on raspberry pi4 to my server.
I opened server port (I choose random high port 69901) And i am successfully connecting to it with username/password i created on server.

When i connect my raspberry py linux softether client from my customer network i get next error:

2020-07-18 12:52:25.490 Connection "CID-402-2DD2379B53" terminated by the cause "A client which is non-SoftEther VPN software has connected to the port." (code 5).
When i try to connect from my laptop (windows softether client) with same credentials on same server from same network it connects normally.
I exported both account settings (linux and windows client) and compared them side by side and they are identical.

I tried it on 3 different locations (home, work, friend) and it is connecting normally both from linux and windows client.
Customer router is simple lte connection.

Does it happen if you use a valid port? Legal port range is 1-65535.

May also not be a bad idea to avoid ephemeral ports if possible: https://en.wikipedia.org/wiki/Ephemeral_port

I am not able to test it on legal port range. But when I export config from raspberry, import it in windows 10 client. it is working.

I am aware of port range but in this case, sadly, it is what it is.
