What is the version of Gluetun

Running version latest built on 2024-08-25T07:04:32.409Z (commit 01fa993)

What's the problem 🤔

Since a few hours my gluetun is unable to connect to my VPN provider (Perfect Privacy, not available in form Dropdown!!!).
FAQ healthcheck and update provider list have been checked and done already.
Update seems to be successful as per „last edited“ of that json file on host.

Seems related to RTNETLINK issue as per the logs. Unsure on how to solve this

The problem seems to be openvpn trying to add an ipv6 address to tun0 and getting denied permission.

2024-08-31T13:18:56+02:00 INFO [openvpn] /sbin/ip -6 addr add fdbf:1d37:bbe0:0:93:1:0:40/112 dev tun0
2024-08-31T13:18:56+02:00 ERROR [openvpn] RTNETLINK answers: Permission denied
2024-08-31T13:18:56+02:00 INFO [openvpn] Linux ip -6 addr add failed: external program exited with error status: 2
2024-08-31T13:18:56+02:00 INFO [openvpn] Exiting due to fatal error

Any idea why that would be?

Otherwise, does one of the following workaround fix it?

  1. Set OPENVPN_VERSION=2.5
  2. Revert to image tag v3.39
  3. Revert to image tag v3.38

Thank you for your quick response!

No, i have no clue as to why it would not allow setting an IPv6. My network allows and is properly set up for IPv6, addresses are issued as they should.
The error appeared after a regular update of the gluetun container, i just did not immediately notice.

1 did not work (same error message)
2 worked
3 worked as well

Thanks!

Ok that is rather strange! On the success tries, for example 2., did you also get an info message similar to [openvpn] /sbin/ip -6 addr add fdbf:1d37:bbe0:0:93:1:0:40/112 dev tun0?

Negative, i only receive /sbin/ip messages like public IPv4 and MTU 1500.

Here are a few examples (redacted ip obviously)

[openvpn] /sbin/ip link set dev tun0 up mtu 1500
[openvpn] /sbin/ip link set dev tun0 up
[openvpn] /sbin/ip addr add dev tun0 123.456.789.555/24

Just to triple check, are you sure if you run the latest image, and set OPENVPN_VERSION=2.5, does openvpn log it's running 2.5 as well? I'm still kind of confused why this would happen, especially since there has not been any change since v3.39 regarding alpine/openvpn/ipv6 really 😕

Sorry, it took slightly longer. I have just checked again.

OPENVPN_VERSION=2.5 with gluetun:latest
YES it is running 2.5 as per the logs but NO it does not work. Everything else was kept the same.

Have you tried adding

sysctls:
  - net.ipv6.conf.all.disable_ipv6=0

to your compose file?

Lol, i have completely missed your response!
Yes, that works with :latest as well.

Interesting! I'm working in #2523 on improving IPv6 support detection, since it's, as you've seen, not really reliable. This would also solve a few issues, including this one.
Can any of you try out image qmcgaw/gluetun:pr-2523 together with LOG_LEVEL=debug and remove the option net.ipv6.conf.all.disable_ipv6=0 to see how it performs, and, if it fails, what logs you get?
