Drop them in the bin ;-) All the pakages i want to handel is IP pakages. I want to make sure nothing with anything else then my MAC-address ever goes out, but I can just as well stop it as change it if it is not IP pakages. > [good expanation removed] > > Every time, the IP package will receive a new ethernet header and your > cablemodem will only see one MAC address. My box route IP pakages between eth0 and eth1. That is working and if I understand You, these pakages do always get the MAC-address of the interface (eth-card) they leaving. Good, then IP pakages is no problem. > I am not very sure about arp-proxy, but a bridge will forward any package > without touching it. Is linux bridging other stuff (then IP) betwen eth0 and eth1? Is that how ARP get thru? ARP is not IP i beleve? If the kernel (or somthing) is bridging, is that possably to turn off? If the kernel is nor bridging, how do wrong MAC-addresses get trhu? Is the MAC-adresses hiding in the data part of IP pakages? Is ARP working in this way? Sorry, alot of questions ;-) Thanks /Lars -- Lars Hallberg Micro++ www.micropp.se/ Freeware * C/C++ * Python * Linux * Debian * HTML * Javascript
