Verizon enabled IPv6 on my Fios home Internet connection today, only 9 years after Comcast rolled out IPv6 on their network! Better late than never I guess. Here’s how to make it work with the OPNsense firewall.
Under Interfaces > WAN:
- IPv4 Configuration Type: keep using
DHCP - IPv6 Configuration Type:
DHCPv6 - Request only an IPv6 Prefix: ✓ (enabled)
- Prefix delegation size:
56 - Send IPv6 prefix hint: ✓ (enabled)
Under Interfaces > LAN:
- IPv4 Configuration Type: keep using
Static IPv4 - IPv6 Configuration Type:
Track Interface - IPv6 Interface:
WAN(which interface to track) - IPv6 Prefix ID:
0
If you have other local networks, like a guest network VLAN, you can assign those interfaces a different prefix ID to keep them isolated.
