>>>  Yes, of course.

But something doesn't work - see my other mail in this thread.
Without any "interface=" line: Thunderbird mailing doesn't work, getting  
a DHCP address doesn't work.

Just tested: without "interface=lo" mailing with Thunderbird doesn't  
work.

But the problem seems to be related only with the existence or non- 
existence of the "interface=" lines.

No such line.

see above: with existing "interface=" lines most things work well.

What still doesn't work: getting a DHCP IP address for the second NIC.

Viele Gruesse!
