@JonathanLee said in Port 0 and IPv4 Great... but hey what about IPv6 or inet6?:
This is ipv4 only.... if you use a ipv6 tunnel broker you will never see an ipv6 rule and guess what the GUI does not allow you to create a floating rule with port zero.
huh.. the rules are there for both IPv4 and v6
cat /tmp/rules.debug
# We use the mighty pf, we cannot be fooled.
block quick inet proto { tcp, udp } from any port = 0 to any ridentifier 1000000114 label "Block traffic from port 0"
block quick inet proto { tcp, udp } from any to any port = 0 ridentifier 1000000115 label "Block traffic to port 0"
block quick inet6 proto { tcp, udp } from any port = 0 to any ridentifier 1000000116 label "Block traffic from port 0"
block quick inet6 proto { tcp, udp } from any to any port = 0 ridentifier 1000000117 label "Block traffic to port 0"
