Exactly how is the ping test being performed?
If the name resolution fails, for instance, the porevious configuration is 
irrelevant.

As Jim mentioned all internal clients if they are securenat clients and
are configured in the LAT  should be able to ping any external machines.
Given that you have enabled ip routing in ISA. Is the gateway of the
internal machines set to the ISA's int interface (i.e securenat)

Thanks

Hi Jim,

Yes, undserstanding that browsing and ICMP are different, if browsing is
possible does that mean I should be able to ping from other clients if
the LAT Host and IP routing are configured?

If the above are configured, what else do I need to do if Iam still not
able to ping from other clients?
