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.
