[SOLVED] No IPv6 traffic through router

[lignumaqua]

I think this problem just started today when I upgraded to 23.1, but it's possible it happened recently with a prior version. Symptoms:

1. IPv6 works fine from router to ISP. ISP assigns an IPv6 address (starting 2605 - this is Spectrum) and I can ping6 from the OPNSense shell successfully.

2. Computers on LAN have IPv6 addresses correctly assigned (starting 2603 - not link local addresses). They show up as leases in the DHCPv6 leases list on OPNSense and display as 'active'.

3. The problem is that none of the LAN devices can access the outside world on IPv6.

EDIT: The outgoing IPv6 ping6 data shows in the firewall logs, but nothing seems to come back


AFAIK I have changed nothing and I can't see where the problem lies. What is blocking the incoming ipV6 data? What do you need from me to help me fix the problem?

Help much appreciated - thank you.

I made one change and things are working again. Specifically I found a suggestion to add a firewall rule to WAN to allow incoming ICMP. I didn't have this before, but adding it now seems to have fixed things. :-)

This thread can be closed - thank you.
