Well,

I tested both version 5.0 and 4.76 - which were known to work at my system 
last year, but currently they show the same behaviour.

Something else must be the culprit (I upgrade glibc from 2.8_p20080602-r1 to 
glibc-2.10.1-r1, this I cannot roll back, kernel sources and headers were 
upgraded too).

What I do not understand is, that the UML is fully reachable and I can browse 
with lynx the internet, but nmap cannot scan it althought I changed the ip 
address to 192.168.1.50 - here are the necessary information :
