No IPV6 Connectivity

[sujop]

I seem to have lost IPv6 Connectivity sometimes after an update...somewhere in the month of May 2023 maybe..not sure when...

I realized yesterday that my opnsense updates where not working...I was on 23.1.9 and Changelog showed that the latest update was 23.1.11. When I manually tried to check for updates, it took for ever and repositories showed orphaned packages. Pinging pkg.opnsense.org did not return any response. However pinging any ipv4 address on the internet worked. I enabled the option "Prefer to use ipv4 even if ipv6 is available" and the updates started working again. Now I am on 23.1.11 now.However the issue with IPv6 persists. pings to internal ipv6 address works.
I obtain IPv6 from my ISP thru DHCPV6. I get an IPv6 gateway and the gateway is also showing in the default routes.

Does anyone has any solutions or workaround?

maybe its an isp issue.
ssh into your opnsense and try to ping ipv6.google.com.

There is an unfixed bug at this time such that sometimes, radvd does not assign IPv6 to clients. You can try if that is your problem by restarting radvd from the dashboard.

Tried it. ipv6 address is resolved however no ping replies.

Tried it...still the same. Clients on the local network are receiving ipv6 and pinging them within the network works fine.

Highly unlikely..My brother is with the same ISP as I..he has no issues with IPV6.
