Created a host type firewall alias and gave it a IPv4 hostname and IPv6 address.
When the alias is used in an IPv4 firewall rule it matches fine. But does not match when used in an IPv6 firewall rule.
Diagnostics: Tables for the alias shows both the IPv4 and IPv6 addresses.
Appears the problem is not with the alias but rather with the firewall rule source address.
When source set to LAN Subnet or LAN Address it does not match.
Setting source to any or Network fe80::0/64 matches.
Seem like source LAN Subnet or LAN Address should match too.
LAN Interface is IPv6 Link Local fe80::1:1 only. Suppose that probably has something to do with it.
The shortcuts for LAN subnet etc. do not currently expand to the 2 LAN subnets yet. That is not yet finished.
