Hi Rolland,
Did you configure the ISA firewall to allow IP routing?
Go to www.isaserver.org and search for "PING" in the Search box and see
what comes up.
HTH,

Yes,
I've configured my clients as SecureNAT Clients ie there gateway is
address of the ISA's internal NIC.
Pinging not possible as all on those clients. Performing a Ping and a
Tracert to my ISP is super fine unlike from the clients. Which gives
time out request.
Cheers
Rolland
