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 -- Jens Rehsack --- http://www.informatik.uni-halle.de/~rehsack/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
