hello i have a strange problem, not sure whats going on. i have a dhcp3-server on a machine. the server is serves to eth1 and eth2 addresses. now i would like to block the server (so that a client cant send a request anymore). but so far i dont even manage to block the dhcprequest with the default policy drop. i have all 3 tables all chains drop i dont have any rule but when i do tcpdump i can see the following 192.168.5.30 bootpc > 192.168.5.1 bootps ...... 192.168.5.1 bootps > 192.168.5.30.bootpc .... what is going on? does dhcp-request goes somehow over layer2? or am i missing the big picture? thanks francis
