If you start using pf firewall with IPv6 enabled the IPv6 addressess are not used: e.g. in case of pf rule: pass out quick proto tcp from $ext_if to any keep state the real rule will be: pass out quick inet proto tcp from "IPv4_ADDRESS_OF_EXTERNAL_INTERFACE" to any keep state the IPv6 address of the external did not take into consideration since IPv6 address not configured yet. >How-To-Repeat: Try using interface names with ipv6 enabled in pf firewall. >Fix: 1.
