More, i couldn't find something that look like that in our servers MAC addresses. The light came after installing Pike's http://modules.gotpike.org/module_info.html?module_id using http://modules.gotpike.org/docs/UsingMonger.html. $ pike Pike v7.6 release 86 running Hilfe v3.5 (Incremental Pike Frontend) > IP.v4.Address(0x6827efd8); (1) Result: IP.v4.Address("104.39.239.216") > IP.v4.Address(0xf738d456); (2) Result: IP.v4.Address("247.56.212.86") It's now more clear that my router bothers about one of Google's IP (216.239.39.104) talking to my ppp0 IP (86.212.56.247) on the ppp0 interface. Now, i can make more tests using ip route get pointed out by redax on #pike: # ip route get 247.56.212.86 from 216.239.39.104 iif ppp0 RTNETLINK answers: Invalid argument Fixing this is a different story, but i can now name what's wrong.
