CGA4332COM not sending Router Advertisements

I'm having problems getting IPv6 working on my Technicolor CGA4332COM router which is in static passthrough mode. I have 5 static IPv4 addresses and a static IPv6 and my router is set up with Bridge Mode disabled.

The CGA4332COM router should be sending Router Advertisement packets out to connected devices, but using Wireshark/tcpdump shows that there are no RA packets coming from the router. I have tried both IPv6 Address Assignment with Stateless(Auto-Config) enabled (it can't be unchecked) and also with Stateful(Use Dhcp Server) checked.

I suspect that since the Router Advertisements aren't working that it's causing DHCP6-PD not to work in my pfSense firewall. DHCP6-PD should give me a /59 prefix which it doesn't. I've read other posts from users that were able to get DHCP6-PD working with a similar setup as mine.

I suspect if we get RA's working (and stateless) then maybe DHCP6-PD will work and we'll get a /59 prefix and we can follow all the other guides online.

We have turned SecurityEdge off for our account.

How can I get the router to start sending out RAs?

Fixed by doing a factory reset of the CGA4332COM. Not sure why it stopped working.

That's awesome! Should I cancel the tech support ticket and list this issue as now resolved?
