Definition of terms:::: udp.single / udp.first / udp.multiple

Hello

Go to System -> Advanced -> Firewall / NAT Settings.

Firewall Optimization Options, is used as standard. Everything works fine, but I would like to understand the following things (diagnostics -> pfinfo -> Search for udp.first)

what does it mean?
udp.first? 60 seconds
udp.single? 30 seconds
udp.multiple? 60 seconds

They have different timeouts. 60/30/60
i know what a udp session timer or timeout is. but i never hear about those different names

I read this:
https://www.netgate.com/docs/pfsense/config/advanced-setup.html?highlight=udp%20single
But does not help.

Thx in advanced
Kind regards
kinch

These values are from the pf firewall, which is part of FreeBSD and the reason for the name pfSense.

Read up more on pf and those values here:
