ISA Firewall with single network adapter - 28.Jul.2003 4:24:00 AM

I have setup ISA server many times with two network adapters, where the ADSL modem or router is connected to the second network adapter.

However, I have an existing network where they already have an ADSL router with IP Address 192.168.0.254. This is the default gateway for all users. I have installed ISA Server but have not configured it.

I only want to have the single internal network adapter on the ISA server, but configure all users to access the net through the firewall, and remove the default gateway settings from their network connections, and instead use the ISA firewall client.

Is it possible to configure internet access and setup ISA server as the firewall without a second network adapter? If so, could I please have instructions?

Thanks

Hi Quamby,

ISA Server's architecture is currently designed such that it requires two interfaces to implement a firewall: One connected to a trusted network, and the other connected to an untrusted network.

HTH,

Bill
