Description Stéphane D'Alu 2020-12-24 12:11:34 UTC

When trying to perform nat on ipv6, I tried the rule:
nat pass on wan0 inet6 from net0:network to any -> wan0:0

But wan0:0 is picking the link-local address

# pfctl -s nat
nat pass on wan0 inet6 from dcb:e130:f4cb:2d97::/64 to any -> fe80::428d:5cff:feb1:a4fd

I've found issue #201695 related to this problem and marked as fixed, 
but it doesn't seem to be the case anymore

I can't reproduce this. Please attach your dmesg, pf.conf and output of ifconfig.

It'd be surprising for this to have regressed as well, because there's a test for the feature.
