While adding some special routes for some machines i figured some errors on the router:
kernel: martian source 6827efd8 for f738d456, dev ppp0
Some comments found on the net stated these were MAC addresses, while it appears those was too short. 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.
