Ah, ok. Understood. So the router is out of my calculations. Remains your
routing table at altijd.

Looks perfectly.

Also. Crazy that it doesn't recognize "localhost".

Yep, ifconfig showed about 200Megs for eth0 and about 140Kilos for eth1,
IIRC (without scrolling up the archive). Hm, currently reading some sites
about "problems with asymmetric routing". All in all very interesting, but not
explaining the problems you have.

No, I don't think that will alter the situation.

Hey, we're not at a Windows box here... ;-) "Ah, TCP/IP doesn't work, oh well,
deinstall, reinstall, reconfigure until it works... *lalala*
(no offense or OS flame war intended, note the smiley)
I've never had to de-&re-install something on Debian up to this day...

Hmm, just out of curiosity, remove one of the interfaces from the "auto"
lines in /etc/network/interfaces, and reboot (so we get a fresh state).
Would be interesting if your net is available then. Maybe it's the duplicate
route that's causing problems (although then there should also be problems
when pinging on the LAN etc.).

Hmm no, after reading your description above I'm pretty convinced that the
problem is somewhere in the configuration depths of the Debian box.

Oh, it's still there, isn't it? But you're right, we'll jump at it tomorrow.

Good night!


PS: If some networking expert wants to jump in and lend a hand, please feel
free to - route & co. isn't one of my specialties... ;-)
