IPv6 Tunnel on OPNsense
Posted: Sat Oct 21, 2023 6:08 pm
Hi all, I am trying to get the IPv6 tunnel set up on the 10 Gb Fiber. I am really confused on how to get it set up on OPNsense, has anyone on OPNsense got it working successfully?
Tunnel or Sonic's native IPv6? Here's a post where I added some screenshots from pfSense which may help. I don't use OPNsense but I assume the config pages would be similar. This assumes IPv6 service is available in your area.

Don't forget you'll need to set your lan/vlan interface(s) to track the IPv6 wan interface. Each lan/vlan then gets a unique prefix ID so you can utilize the /56 that Sonic assigns you. Enable RA (I use assisted mode) for those lan/vlan interfaces and you should be good to go though you may have to reboot OPNsense once your config is set.
