Port 0 scanned however no way to enter alias with it

[JonathanLee]

Hello fellow pfSense community

Is there a way to enter port 0 for rules on pfSense? I can create a block alias with it, again https://www.grc.com/intro.htm

Shields up scans for port zero. Shouldn’t pfSense have the ability to block it? Or am I just going tinfoil hat mode again?

@JonathanLee its already blocked anyway

Look in the full set of rules.. The gui doesn't show all the rules

# 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"
