Checking with the internal log of the router confirmed the suspicions of 
people answering my question: The adsl router is responsible for the 
problem with the 255 address. It seems it cuts out these addresses as 
some kind of "attack". No changes in configuration (firewall, protection 
and so on) on the router itself disables it. It seems I will have to 
live with it ;) Oh well...
