Hi, I cannot get my head around why I cannot get this working on my Synology NAS.

If I run

docker run -it --rm --cap-add=NET_ADMIN -e VPNSP=mullvad -e VPN_TYPE=openvpn -e FIREWALL=off -e OPENVPN_USER=[REDACTED] qmcgaw/gluetun

on my Linux Mint computer it works just fine.

Running the same command on my Synology NAS with DSM7 on the same network I get this (see below).
Any idea what I am missing?

I recently did a large refactor, maybe test with image tag :v3.26.0 to see if it works?

Otherwise try with a particular server filter (like COUNTRY=netherlands maybe that's a bad server for some reason.

Same result
openvpn: UDP link local: (not bound)

Could it be maybe a Synology DSM7 specific issue?

After some tinkering I have it working.
The country filter worked.

Thanks!
