You can't.
ICMP as a "heartbeat" is useless, since it tells you nothing about the state of
the desired service (web server, in this case).
Better that they use a "HEAD" request to the web server. THis way, they not
only know the TCP/IP stack is running (all that ICMP gets you, BTW), they also
know the web site is alive and well.

All,
I set up ISA Server Standard Edition now and users needs to check
heart-beat to internal web server from externel network.
ISA seems cannot make server publishing rule with ICMP.
How do I set up ?
Network:
Pinger client --- internet --- ISA -- Web Server (SNAT client).
