Browse All TopicsDear All ,
I had a network managed by DC , & ISA Server , Recentrly i got a new internet connection for Doc. Controllers , I need to configure them to work on ISA server using the new internet connection and the other users use the same ISA server but for the old Internet Connection .. and i would like to prefere to keep the Users with the new connection in the same subnet ..
Note Server is having 4 nic , two of them already configured fo the old internet connection & the Other Users .. other 2 is ready for any configuration ..
Seconf thing .. I need unauthinticated users to use also the ISA server on the old Internet Gateway ,, Namely they aren't connected to the dc and they need to access internet ,, and i need to controll there access through that ISA server ..
I know its pretty hard to do so .. but i know some one here could help

Two questions should be just that - two questions. However, as it is Christmas....
Two internet connections is a non starter through ISA - as I say, basic ISA setup guidance notes explain this. The only time two connections can be used is if you were routing traffic out based on IP addresses as you could use the OS routing tables - and you would need a third nic in the ISA. Anything else, forget it.
The second is a no-no also for the same reason. ISA uses the routing tables based on the host OS - it is not a router itself, therefore it cannot send one group of users one way and another group of user a different way - regardless of whether they are authenticated or not.
As Keith has already said you cannot achieve this via ISA. You will need to implement a router infront of the ISA firewall which deals with the load balancing / failover for the 2 internet connections. This type of router will of course require dual wan ports / ATM that supports load balancing / failover.

One way I can think of doing it is via login script (set in AD). You could use a Kix Script to define a different default gateway for the any users that were domain members. This is demonstrated here:

That said you would still need an additional ISA box to do this for the 2 separate gateways.
If cost is a prohibitive issue and you want to impose content filtering, then look at (google) Squid/Squidguard/DansGuard
The other option is to build the second ISA and use Group Policy to specify a Proxy server in the browser settings. Assuming all users use IE that should work.
Yes, it is standard capability with two ISA's (naturally) because you are setting up two environments, regardless of whether you put them into individual or dual arrays. As long as you are happy to pay for licensing two ISA servers. However, this was not the question asked. Given the environment in place and the approach currently being taken, it cannot be done.
Putting in a different environment, by buying new, additional hardware, software and new licenses etc then frankly, anything can be done.

Its quite likely that this suggestion will not be suitable for your environment ,as you sound like you mainly utilise Microsoft however:
In addition to being able to policy route traffic out specific interfaces, you need to be able to tag the packets as they come in and keep track of the connections and return them out the correct interfaces.
One such solution is to replace the ISA server with something like OpenBSD / FreeBSD + Squid + Squidguard / Dansguardian. In addition to that, the easiest solution would be to put the users in specific ip ranges (i.e. use DHCP reservations)
alternatively
I implemented such a system for a customer of mine a couple of years ago. They have multiple tenants sharing an office building. They provide internet access to each tenant, with multiple internet connections for failover and load balancing.
I achieved this by implementing a FreeBSD server, with multiple coppies of squid running on it (in Jails though you shouldn't need to go that far) listening on differant ports.

Won't happen - Not possible through ISA. Basic ISA README file in the setup guides.
