[SOLVED] IPv4 has internet with these rules but IPv6 does not?

[Norman Uittenbogaart]

With the below firewall rules, the machine can contact ipv4 addresses without any issue.
But for some reason ipv6 can't get through. (standard policy is drop in / drop out)

When I enable the first 2 lines, Ipv6 has internet again.
It does not seem to block anything in the logs, am I missing something?

The VPN is docker only.

Ah I see I removed HTTP and HTTPS here on this screenshot.
They where on there and when added again, still doesn't work (for IPv6)

Hi,
please make sure that the log level is set to some value different then nolog in the Datacenter->Firewall.
Best is probably to debug with socat https://linux.die.net/man/1/socat

Problem is solved, there was a unconfigured test server of OPNSense running in the network which as a default apparently as a router advertisement on. (even if DHCP server is off)
As soon as this was shutdown, it started working again.

Glad the problem is solved! Please mark the thread as solved for others to know what to expect.
