I have ISA server as second firewall. I cannot ting from front end
firewall to a host on internal network. Is it possible to allow this and
what I should do if yes.
Scenario:
ISA has 3 interface: internal 172.17.1.2, external (to front end FW)
10.17.1.2 and DMZ 172.18.1.2. I can ping from ISA out and I can ping
external interface of ISA from front end FW. But I cannot ping a host on
internal network that has IP 172.17.1.13.

Thanx in advance for any help.

PS Help if u can but just don't ask me why do I need this:-)).
