I have SBS2003 domain with another standalone server 2003. I installed an
external NIC (2nd NIC) in the Server 2003, connected to a DMZ port on a
firewall, and have NICs set up as follows
Internal NIC - IP:192.168.16.4, SN:255.255.255.0, DG:Blank,
DNS:192.168.16.4,192.168.16.2
External NIC - IP:192.168.20.2, SN:255.255.255.0, DG:192.168.20.1,
DNS:192.168.16.4,192.168.16.2
In IIS, the websites are pointed to the external NIC, and have been restarted.
In DNS, website domains are pointed to 192.168.20.2.
Static route between 192.168.16.x and 192.168.20.x is created.
The firewall DMZ port is set to allow HTTP/HTTPS traffic through to the DMZ
port, and that appears to be working fine. However, the website will not
respond - it appears that something is blocking it from responding back to
the firewall.
In RRAS, I do not have NAT/Firewall installed, is that necessary for
operation? Or is there something else I am overlooking?
Thanks
Paul

We need more details to help you. Where do you access the web? Can you telnet the port 80?

I can not telnet the port 80 from the internet.

Have 5 static external IPs available.
Inernet>cable modem>firewall(Sonicwall TZ170)>LAN>Domain.

>DMZ>Server2003 Ext NIC.

Firewall has LAN ports and a DMZ port; LAN ports network is set at
192.168.16.0/255^3.0 and the DMZ port network is set at 192.168.20.0/255^3.0.
The firewall's LAN IP is 192.168.16.1^4 and the DMZ IP is 192.168.20.1/255^4.

I hope this helps - I am not really sure what you need so I take my best
