Hi there,
thank you for the quick answer.
I downloaded and burned the knoppix dvd just yesterday. The version, according to the version document on disk is "5.0.1 2006-06-01".

My machine is a AMD Athlon 3200 XP+ on an Asus Board A7N8X with an nVidia chipset and two network cards on board.

Ethereal revealed, that only konquerer is trying the correct connection creation when contacting a website (getting the ip adress from the router and sending SYN-packets, receiving ACK packets and so on).
Firefox and every other program i tried so far (Lynx, gaim ... uhm ... that's it but still), tried to create a connection to 1.0.0.0
That strikes me a bit odd.
It seems, as if all other programs send DNS request, that get 1.0.0.0 as an answer from my router

If i try nslookup from a console, i get the correct answer though.
Hm ... that looks as if these programs need some other DNS configuration? Or they send wrong packets to my router?
Sometimes Ethereal says something about malformed packets, but that is indeterministic in relation to the connections that work and those that do not.

Anyone an idea, where to look for THAT specific problem?

Thank you in advance, your help really is appreciated
