Assign IPv6 address to WAN with PD-only ISP
0%
Description
When the WAN interface is set to "request only an IPv6 prefix" (which is required by some ISPs), no IPv6 address is assigned to the WAN interface other than a link local address. This results in needing to use the LAN IP for requests such as VPN connections from the WAN, and VPN rules need to be manually added.
Would it be possible to have PFsense assign an address from the prefix to the WAN interface in "request only an IPv6 prefix" mode?

It's not viable to have addresses from the same subnet on two different interfaces. It places them into the same subnet, and isn't supported.

I was thinking a something more like how track interface works for LAN interfaces. AS long as the ISP assigns a prefix < 64, such as /48, could we do something like the LAN track interface feature for the WAN interface? Even if it needs an entire /64 subnet it'll still be useful.

A workaround is creating a VLAN interface on the WAN interface and having the VLAN interface track the WAN interface for its IPv6 configuration. Traffic is then routed between the WAN-VLAN and the WAN. But it would be nice if that wasn't necessary.
