I have been trying, unsuccessfully, to use IPv6 with Voyager (both DHCPv6 PD and SLAAC).

I am hoping someone is using the ERL or pfSense with Voyager, and can send me details of how their system is configured (WAN settings and any additional firewall rules).

I have followed @michaelmurfy's detailed IPv6 ERL guide, without success. I had issues with IPv6 during the Bigpipe trial, where everything worked (at least with IPoE and pfSense) up until my connection speed was changed. I have confirmed with Chorus that my ONT is not one of those affected by the IPv6 DHCPv6 PD issue, although that issue shouldn't prevent SLAAC from doing its thing.

Voyager supplies a Huawei router which requires only a few trivial steps to set up IPv6, but I'd rather not buy or rent another router just to confirm where the problem is occurring.
