Urgent Please Help DMZ Config - 4.Jan.2007 8:32:38 AM

Dear All,

On my ISA box I have created a DMZ network, using IP range 10.10.1.0/24

as well as creating an Internal network, using IP Range 192.168.1.0/24

So far the pc on the Internal network can ping and connect to the pc on the DMZ network just fine, and vice versa for the DMZ connecting to the pc on the Internal network.

The problem I'm having is that the DMZ can't connect to the internet, it can't even ping the NIC in the ISA server which is being used for the DMZ, it can't ping the NIC in the ISA server which is being used for the Internal network either.

I don't understand what I have done wrong?

My Firewall policy rules for now, allow all traffic from the DMZ to External & from DMZ to Internal

And my network rules are: DMZ< >INTERNAL route
DMZ<>External nat

I also have: INTERNAL< >DMZ route & INTERNAL< >EXTERNAL nat and the pc on the internal network can connect to the web, and as I stated earlier, it can connect to the pc on the DMZ and it can ping both nics in the ISA box.

Lastly, the GW address for the pc on the DMZ is pointing to the IP that is being used by the nic in the isa box for the dmz so i'm sure it setup right.

I would really value some help as I'm going on holiday in a few days and really need to get this working quick :)

Kindest Regards,

JIL

Just to let you know that I have sorted out the ICMP ping issue, from the DMZ (what a donut) but can't get web access yet? looking through system policy rules to see if there is something fishy going on which I have missed, but if someone can point me in the right direction that would be great, ta

Problem solved,

Sorry guys, basically under network sets, under the DMZ network, I didn't have 'Enable web proxy client connections for this network' enabled, now it works, again just a silly user error :)
