Subject: Netfilter CPU Cycles
Date: Fri, 20 Feb 2026 14:41:25 -0700 [thread overview]
Message-ID: <28545c101b8fb76bb1382ed2abc46890@autodiystuff.com> (raw)
When a hook is running (iptables etc) and there are no rules associated
with an interface (eth1), does Netfilter in kernel still burn cpu cycles
to know there are no rules? Does this behavior change if eth1 is promisc
with no ipv4/v6 vs having assigned IP?
Thank you,
MB8
