I built a server on Ubuntu 20.04 and installed Plex, Nextcloud and Wireguard.
It works almost perfectly, thank you Xiao for all the tutorials.
I’m facing a problem since months and made a lot of research on internet without finding the solution.
My problem is that I cannot connect to Plex, Nextcloud and also Wireguard from certain network. If I use a VPN like ProtonVPN it works. The problem seems to be linked to the public Ip from the client side.
Finally I think that it is linked to the fact that the client and the server have the same public default gateway.
My server public IP: A.B.C.056 with default gateway on A.B.C.1
The client public IP: A.B.C.125 with default gateway on A.B.C.1
Could it be the problem? And can some help me, I’m turning crazy.
Thnak you in advance
I have also tried from a friends wifi with same ISP
His public IP: A.B.C.074 with default gateway on A.B.C.1
–> It doesn’t work
My two friends and me have the same ISP and live in the same area. First I tought that the ISP was the cause but from two other friends wifi with same ISP it works properly. (They live not in the same area and their puiblic IP is totally different.)
