the method above accepts traffic but does not send anything back.

a recent commit enabled the following method of blocking traffic
entirely (it never gets passed to userland):

	# fuck bytedance
	aux/dial -e -o hangup 'ipmux!ver=4;src=47.128.0.0&255.252.0.0' rc -c 'echo 0 > /srv/blocked.47.128'

no dial process is left running, we just hold open the fd.

remove the block like so:

	; rm /srv/blocked.47.128
