ISA 2004 - Can't browse the webpage hosted in internal web server network
Posted on 2006-11-01
Hello, I have the following question. Let me first of all inform you of my home network set up.
My Network consists of the following:
Router - 172.16.1.1
Primary Domain Controller Server - 192.168.0.3
Web Server - 192.168.0.4
Exchange Server - 192.168.0.5
ISA 2004 Server - 192.168.0.1
I have two subnets connected to my ISA server (2 nic cards)
Nic 1 - Internal private subnet IP address - IP 192.168.0.1
Nic 2 - External connection to the internet form the ISA server 2004 - IP 172.16.1.2
Nic 2 - points to the default gateway which is the router - 172.16.1.1
Now the quesiton, everything works just fine on my network, I have told ISA 2004 to allow ports such as 80, DNS, IMAP etc... so I can browse the web, send/receive emails no problems. Except, im hosting my personal webpage on my webserver that resolves to a domain name, the problem is that I cannot view my website anymore after setting up the ISA 2004 server, for example if I type in the domain name www.mydomain.com it no longer resolves to my Primary Domain Controller where im also running the DNS service.
I did a tracert to my external DNS and it seems to hang up at the router. I have tried setting the router to a DMZ with no help, I have also forwarded the DNS ports on the router to my external Nic card in the ISA - 172.16.1.2 with no help. Im stuck here.... im not sure if I should open up any other ports on my ISA server to make this work? can anyone be of assistance?
