Thanks for the reply. tcpdump on the destination shows the echo request inbound but no echo reply. If I fping myself from the same host to the same destination then I see the echo request and the echo reply. The only thing I can see different in the dump is that the sequence number is different. The device I'm pinging is a check point firewall. Maybe it doesn't like that the sequence number is out of sequence or something. When I fping with 10 packets the sequence numbers are 0 through 9. When Smokeping does it's thing the sequence numbers are incremented for each device pinged. I'll see if I can enable some logging on the FW for this ping traffic. _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
