Description

When enabling reply-to rules on WAN,
Where the WAN is PPPOE, configured by SLAAC,
When you add a rule, the reply-to address used is that of the physical interface, and not pppoeX.
This only applies to ipv6 rules.

With reply-to disabled:
pass in quick on pppoe1 inet proto icmp from any to 87.252.44.195 keep state label "USER_RULE: allow inbound ping"
pass in quick on pppoe1 inet6 proto ipv6-icmp all keep state label "USER_RULE: allow inbound icmpv6"

With reply-to enabled:
pass in quick on pppoe1 reply-to (pppoe1 212.42.162.226) inet proto icmp from any to 87.252.44.195 keep state label "USER_RULE: allow inbound ping"
pass in quick on pppoe1 reply-to (sge0 fe80::f2f7:55ff:fe0c:5700) inet6 proto ipv6-icmp all keep state label "USER_RULE: allow inbound icmpv6"

sge0 is the physical WAN interface.
The gateway IP is correct.
