[kajvans]

Hai everyone,
I am trying to access sabnzbd behind gluetun but when i try this i get: "site not available"
My services in the docker network have no problem connecting to it only when i try to go to the GUI from another computer it wont work.

I tried disabling the firewall but that did nothing.

In the logs of gluetun i dont see anything unusual but maybe i missed something since i am not an expert.
Sabnzbd logs also dont show anything that might reveal the problem.

Things i have tried:

1. seperate compose files
2. disabling firewall
3. using service:gluetun instead of container:gluetun
4. switching ports

the problem is not only with sabnzbd but also qbittorrent so i think it is a gluetun problem here.

I think you may need to add in your environment section:

• FIREWALL_OUTBOUND_SUBNETS=

Otherwise it won't allow your LAN connection into the docker network gluetun runs. Put your subnet(s) as the argument

I am not a dev, just a user, but hope this helps.
