[Just for the archive]

Ah great, folks, thank you. Now it works perfect.

My problem was, that the DHCP-server on the host receives
DHCPDISCOVER and sends DHCPOFFER. But the box itself receives no
DHCPOFFER.

Shortly, the DHCP server must be binded on my br0 (too), and now it
works - nearly.

This

  Oct 23 00:56:17 [kernel] martian source 192.168.0.2 from 192.168.2.50, on dev 
br0

was a faulty routing entry only.

Now it works - really(!).


Greets,
Tom
