Subject: dhcp weirdness with iptables
Date: Tue, 23 Sep 2003 16:09:33 +0200	[thread overview]
Message-ID: <20030923140933.GA22498@phys.ethz.ch> (raw)

hi

i get my ip address from a dhcp server. i have experienced strange behaviour of
my iptables-firewall:

it seems that the dhcp packets seem to be unaffected by the firewall, because,
no matter how restrictive i setup the firewall, the udp packets coming from
port 67 on the dhcp-server and going to the local port 68 pass through. has this
something to do with the linux socket filter (CONFIG_FILTER in the kernel
configuration), which is needed by dhcp to work correctly?

thanks

benoit steinmetz.
