ER605 2.2.2 update - no incoming IPv6 packets?
I recently upgraded to the new 2.2.2 firmware, after previously being on the beta version. Since updating I've noticed that no incoming ipv6 connections are getting through, everything is timing out at the firewall. I'm using the same access control rules that were previously working with the beta firmware, allowing certain protocols through to various hosts, and blocking all else. To test, I removed all rules and readded them, and then even added a rule that allowed ALL traffic in all directions to/from all hosts at ID 1, but even this didn't work - port scanners couldn't detect any ports being open on ipv6. Also, incoming ICMPv6 packets are also not getting through, and there doesn't appear to be any way to control these anyway that I can see, but from my memory I believe they were all working previously.
ipv4 connections and port forwards are all working perfectly.
Has anybody else had a similar issue and if so, have you been able to solve it? I haven't done a factory reset as yet because I'm very loath to reconfigure everything - I have a LOT of settings changed. Would a factory reset and re-upload of a saved configuration possibly fix it? I suppose it's possibly that my ISP has an issue with incoming ipv6 connections, but this seems far less likely than a router issue, and it only seems to have started happening since I upgraded the firmware.
Thanks!
