What I want to do is simple: All packeges leaving my eth0 interface shuld have the MAC- adress of my eth0-card. Regardles if they is orginating att another machine and only routed trhu this machine (who is a gateway).
However 'easy' it is, I don't know a way to do it. Not in 'postrouting' filter roules, not in device configuration, nowere else :-( The feature shuld be usefull for completly hide NAT-ed subnet on a local net e t c. Me myself need it as my upstream network device (A radiomodem/link) only can remember one MAC-address so the upstream net must beleve my complete net have one and the same MAC-address. I have solved it by Pryxy-ARP cacheentrys. That fixes the packages that matters. Howewer, evrytime the upstrem device (radiomodem) hangs, my ISP blames my outgoing pakages with 'wrong' mac-addresses. I'l be happy to remove that excuse ;-) BTW1, If I have to atack the source to fix this, how do i find out if such hack can be of intrest upstream (so, maybe, I dont have to redo it for every upgrade) BTW2, I have not made my Proxy ARP cacheentrys workin on a 2.2 kernel, so my GW still runs 2.0. Have not tryed hard with this, so, if someone have Proxy ARP experiens in 2.2 or 2.4, pleas tell me ;-) TIA /Lars -- Lars Hallberg Micro++ www.micropp.se/ Freeware * C/C++ * Python * Linux * Debian * HTML * Javascript
