Hello,
I have a problem with IPv6 firewall rules. I use OPNsense 17.1.10-amd64.
If I add an IPv6 TCP rule from a LAN net to * with gateway default/* everything works fine. But if I change the gateway in the rule to my IPv6 Gateway (I use a Hurricane Electric 6 to 4 tunnel) no IPv6 connection to the internet from that network can be established.
In the log I can see that the TCP SYN/ACK segments are blocked by the firewall. See screenshot attached.
Can anybody give me a hint how I can solve that problem?
Thanks in advance,
fuerni
