If you stop the ISA services does everything work fine?

I'm trying to install a Frontend Exchange Server in the DMZ zone of the
ISA firewall. I followed the instructions from a microsoft white paper
and it says to open the following ports on the firewall: 443, 993, 995,
25, 80, 143, 110, 389, 3268, 88, 53, 135, 1024+, 445. I have created a
rule to open all these required ports for the Frontend Exchange Server.
However when I log in to the Frontend Exchange Server I try to query the
Internal DNS Server within our LAN by performing a ping request or
nslookup. For some reason I am unable to reach the internal DNS server
or any server in the internal LAN. Can anyone help me or provide me with
any details to help solve my problem please??
