when the pings fail, what does snoop on the interface report?
do you see any interesting changes in the output of 'netstat -s -P [ip, icmp]'
of the target? Can you run the dtrace script below below to help figure
out if the problem is in ip or lower down in the stack?
#!/usr/sbin/dtrace -Cs -
ip_drop_input:entry,
arp_drop_packet:entry,
ip_drop_output:entry
{
printf("reason %s", (string)arg0);
stack();
}
