I am trying to publish an application server to communicate with a website hosted by a third party company. I figured out that with ISA 2004 and a 2 NIC setup, that I should be using ISA and not RRAS to accomplish the port forwarding.

 

So, I created a new protocol definition (TCP 5552 Inbound), and then used a Server Publishing Rule.

 

My Server Publishing Rule tabs look like this:

 

Action = Allow

Traffic = [protocol definition referenced above]

From = External

To = 10.0.59.25 [IP address of app server]

Networks = External [public IP address of 2nd NIC on SBS server]

 

2 questions:

1) Should I reference a different public IP address on the Networks tab? We have a couple not in use. Advantages/disadvantages?

2) If I want to limit IP addresses that can connect to this server, is a "Computer Set" the best way to add the IPs provided by the other company? They've provided a range plus two additional IPs. Didn't know if Computer Set or Address Ranges was best.

 

Thank you,

Thank you, Kevin, for your comments. When one hasn't done something before, it's nice to have someone else look over your shoulder.
