Just to clarify: your symptom is that certain machines do not respond to PING
requests to themselves, but can PING other machines? My initial reaction was a
name resolution problem - are you using DNS? Does the "problem" server have a
DNS entry with a valid entry for that server and/or a HOSTS table entry for
itself and/or a local "hostname" defined? Can the server PING itself by IP
address? Are these servers multi-homed? Sorry if I'm just asking the obvious.
I strongly doubt that the firewall is implicated, as a local PING request should
never get past the redirector on the local machine.
Please post more info if I've misunderstood the question.

Subject: [FW1] Question on NAT
I have run into a strange problem using static NAT on a few Internal/Dmz
devises on my network. It appears that the devices that have NAT applied to
them can not see themselves, however all other devices both internal and
external can see them. From any station in my network or on the Internet I
can ping the external IP address that I have created, but from the devices
themselves I get a request times out back. The NATed devices can ping all
other devices both internal and externally. The Firewall is version 4.1
running on an NT 4.0 server with service patch 6a. I am fairly new to
working with Checkpoint, so any help would be greatly appreciated.
