Re: HP Unix ping
and welcome to the forums !
If your problem server (serverA) can get the address of the target server (ServerB) resolved, but no response comes back from serverB, I would suspect a firewall stop.
Can you ping/telnet etc from serverB to serverA ?

Re: HP Unix ping
The fact that other machines in the same subnet can monitor this customer won't prove anything.
The firewall rules for monitoring might have been done on a per-host basis, and the IP address of the HP-UX has been missed or accidentally deleted from the firewall configuration.
Identical traceroute up to the firewall suggests that the HP-UX server's own network settings are probably OK.
If you can get confirmation that the packets are reaching the firewall and are correctly addressed at that point, you know the problem is not with the HP-UX. The firewall admin could also tell whether the packets are going through or if the firewall drops the packets right there.
If all this is OK, the next questions will be: does the firewall see the responses from the customer machines and does it allow them to reach your server?

Re: HP Unix ping
customer system from the HP box and see if
your firewall logging these connection attempts.
If not, could be a problem with the routing
configuration on the HP box. If the firewall log
shows the out-going connection attempts from
HP box, then check the log again to see if you
have incoming replies from the customer site.
