Can someone give me some iptables rules for specifically allowing dhclient to function properly with a cable connection. I have been reading about how DHCP works and I don't understand it fully. I basically want to keep my existing firewall, which works fine for a standard dialup modem connection, but will have to add some rules to allow DHCP. I only want to "weaken" my firewall as much as I have to, to make this work. Thanks. Mark.
