How did you test 'connectivity to the log box'? Does fxp0 and the log
box have IP addresses assigned, and you can ping between them? And you
see the ICMP echo requests and replies when you tcpdump on fxp0?
One reason you wouldn't see packets dupped would be if fxp0 wasn't up,
i.e. if you don't have at least 'up' in /etc/hostname.fxp0, and
'ifconfig fxp0' doesn't show 'flags=<UP>'. But in that case, you'd have
no 'connectivity to the log box', unless you merely verified that a
cable is plugged in :)
