ISA blocks inbound pings; that a good thing, since one of the simplest DoS
attacks is a ping flood.
If you're trying to get LAT hosts to ping outbound, put a check in "Enable
IP routing" in IIP Packet Filters" properties.

NO I have done that all internal machines can ping the internal address OK,
its all the external addresses we have for web hosting etc that become
disabled eg. if you have a ping ... -t command and stop the service the
ipaddress becomes alive again. Any ideas?

I take it you mean internally, in which case create a client set for the
addresses you want to use.
