Generally , IP adresses , where the host-address part are all 1, are used as the broadcast address. But this is AFAIK not mandatory, U could use any other address as broadcast.
But broken software may rely on the default behaviour and may not work correctly with 'weird' settings.

As for Your mail : please use full IPs ( 212.0 and 215.255 - what are those ??? ) they are probably the last two bytes of addresses , right ?
and also use numerical addresses , not DNS names ( gw-ostenfeld.k- , gw-bergsoe.k-ne, carlsberg5.kamp etc. )

Now the answers :
1. If all Your linux boxes respond to 212.255 , then they obviously think that this is the broadcast address, which it is off course not . Check their network setup ! if U dont specify the broadcast address explicitly for the ifconfig command then it will pick x.x.x.255 for C class networks, but isn't correct for Your network !
Weird that they dont respond to ping from ormen ...
Do they correctly respond to the real broadcast address 215.255 ???
