ISA Proxy and Firewall Client

I am new to ISA Server Standard and I have been reading a lot about it. I am a little confused about client access.

I am running ISA on a member server with nothing else on it. DHCP and DNS is on another box and Exchange is on a third box.

Regrinding Firewall client: What is the benefit of it? Do I need it? If so, would I have to run around to install on 80 users?

Regarding the proxy settings in IE: Is there a benefit to using a clients proxy settings verses the DHCP? Can I expect the same cache and reporting benefits if I want to use DHCP?

Thanks for any clarification.

Hi Bizzie,

First off I would like to recommend a site that many people use to figure out common and not so common issues with the isa server. www.isaserver.org

Now on to your question.

If you are providing simple http web traffic access to your users then you do not need the firewall client you can just point the web browser proxy setting to the isa server. The web proxy client will handle the following application layer protocols:

Http
Https
Ftp
Gopher

For any other protocol you will either have to use the firewall client or set the computers up to be a secureNAT client.  Setting up Secure NAT does not require you to install anything on the client pc.

As for using DHCP to setup the proxy setting. I have done this and sometimes had delays finding the ISA SERVER, also if your DHCP server goes down then the client pc's will not be able to find the isa server.  If are running Active Directory then you can specify the internet explorer proxy settings in group policy. I have found this to work better than any of the other methods.


Hope this Helps,

Ryan

Thank you very much.

By the way, I have been to isaserver.org and while there IS a lot of information there, they did not answer the question in simple terms as you did. Most tech sites that I visit make assumtions that if you are there you have a certain understanding to begin with.

No Problem! If you have any more questions let me know, ISA Server is a great program but it's also a pain in the ass sometimes. :)

Thanks,
