Re: Multi-Homed disjoint network - SBS Premium and ISA Server 2004

Take a nic out.

Use the CEICW to configure the ISA 2004 with 2 nics

Get the setup to work

Then add the third nic for whatever you need.

I just setup a Windows 2003 SBS Premium Edition for my office. We have two internet connections, both using routed internal IP Addresses for the desktops and server. I would like to allow certain services through on one network card, intranet on another, and other services through on the other backup internet connection.

I have tried configuring this many times, but am unsure how to configure ISA Server to allow the traffic right.

I have three network cards in my server as follows:

1st Network Card
IP: x.x.x.3
Subnet Mask: 255.255.255.128
Gateway: x.x.x.1
Planned Usage: Internet access from the outside world to ONLY Outlook Web Access.

2nd Network Card
IP: x.x.x.5 (in same range as above)
Subnet Mask: 255.255.255.128
Gateway: x.x.x.1
Planned Usage: All intranet traffic, including traffic from 4 other outside agencies hooked via T1 on different IP ranges and subnets.

3rd Network Card
IP: y.y.y.86
Subnet Mask: 255.255.255.240
Gateway: y.y.y.81
Planned Usage: Remote administration and user access via Remote Web Workplace and built-in SBS "Connect Computer" capabilities.

The Problems I have:

1. Routing issues. Not sure how to setup ISA Server 2004 to allow all this different traffic sources to specific resources.
2. When putting information into the Network cards I get warnings about multi-homed and disjoint networks not working correctly. How do I solve this?
3. How do I ensure that Exchange is sending and recieving mail through the .3 interface only?

Any help configuring this would be greatly appreciated.
