 Posted: Mon Aug 26, 2024 8:36 pm Post subject: Unable to reach remote container port behind VPN |
 |
|
Hello folks,
I have a small server which acts as an OpenVPN server and a ZNC server, among other things. The ZNC server runs in a docker container and is accessible locally via the server host IP.
Server IP: 172.12.0.118
Server Domain Name: vswitch0.lan
OpenVPN network: 10.8.0.0/32
ZNC container IP: 192.192.24.24
ZNC Port: 6501 / UDP
So, locally I would basically connect to the ZNC server via vswitch0.lan:6501. Unfortunately no matter what I have tried so far, 6501 looks to be closed from behind the VPN.
Some context from the server side
