If what you mean is to deploy isa server 2006 on windows 2008 r2, its not a supported os version nor scenario. if your os platform will be 2008 windows server then you can look at deploying tmg. there a re good guides here http://technet.microsoft.com/en-us/library/cc441445.aspx

however if your os platform is still windows server 2003, yes it can work and yes you can use it as your firewall and proxy. to achieve that you can deploy the edge template and following linglom’s blog will help you through the deployment.

I was windering if you could assist me, I have decided to rebuild my home office environment to Win 2008 enterprise R2. I nned to use Isa as a transparent proxy so t hat all my client pc’s can just pass via my server. I have 2 nics one on a 192 range going to my router and the other nic for my internal LAN on a 200 range. can yoou please advise me if I can use the ISA sewrver as a Firewall and proxy and if so which config should I use (never used ISA before but have been told this best fits my needs) all the help would be appriciated.

hope u help me

Note: If you have two firewalls, why don’t you put IIS on DMZ?

I have tried to access http://10.249.8.140 from a client computer in local network. I not able to access the website. once i can access it locally , I am planning
to access through live IP.

pl guide.

There is little bit change of IP address for
(External NIC of ISA2006 ) as local IP : 10.249.8.140
later on one live IP is routed to local IP(10.249.8.140)

1.

I have followed back Fire wall Network Template to build network layout, In the Internal network IP address range i have kept (from 10.249.8.1 To 10.249.8.255)

2.
I have crated a external web listner for port 80
External web 80

3.
I have crated a web publishing rule – web(10.249.8.134)
with publish a single web site option.

on internal publishing detail
Internal site name: abc
Use IP address: 10.249.8.134

on public name Details page
Accepts request for: This domain naem (type below)
public name: 10.249.8.140
path: leave empty

on Web listener- (External web 80) as created on step 2

4.

For network rule

I have used NAT for connectivity between Internal and external network.

* Do ensure that you do not have a gateway specified on the internal NIC of the ISA server.
* Also if you want the internal network access the Internet through ISA Server, you need to add the internal network address range to the ISA Server. Otherwise, clients in internal network wouldn’t access the Internet.

Ok.

Your ISA 2006 step by step note is very helpful
Here is the rough diagram of my Network

Will Back Firewall Network Topology work for this.

Could you please tell the step by step approach for this
