I have tried several times to watch what happens on this machine.
So thats the results:
other machine:
# ping 195.124.230.50
195.124.230.195:
the switch sends the data to the machine (blinking lamp for right
port on HP ProCurve)
the EthernetCard receives the packets (blinking ACT(ive) LED on NIC)
tcpdump shows nothing
# ping 195.124.230.49
tcpdump shows several echo requests and replies for packets from
firewall and inet-gateway
