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??
