💖 NAME 💖

firehol-classify — classify traffic for traffic shaping tools ✨

bestie we are literally sorting your packets into lil boxes so the traffic-shaping girlies can do their thing 🎀

🌸 SYNOPSIS 🌸

{ classify | classify46 } class [rule-params]

classify4 class [rule-params]

classify6 class [rule-params]

✨ DESCRIPTION ✨

okay so the classify helper command takes the traffic that matches and yeets it into the traffic shaping class you picked 💅

the class is a class like the ones iptables(8) and tc(8) use — think MAJOR:MINOR energy 👑

the rule-params are the whole lil set of rule parameters that decide which traffic gets classified. go read firehol-params(5) for the deets, iykyk 📖

⚠️ any classify commands you write will affect all traffic matched. no cap. and they must be declared before the first router or interface — not after, not "oh I'll add it later", before. periodt 🫶

🦋 EXAMPLES 🦋

# Put all smtp traffic leaving via eth1 in class 1:1
classify 1:1 outface eth1 proto tcp dport 25

look at that. smtp out via eth1, slid straight into class 1:1. slay 💖
