Client cant access internet via ISA 2000

Hi,

We have an ISA 2000 array and one of the developers has a script that he is testing on his machine which basically connects to a website to down download some files. He has specified the IP/Port of the proxy in the script, but for some reason it wont go through.

If he takes the proxy ip/port out of the script, we can see the machine trying to access the internet as its hitting the corporate firewall, but the firewall is blocking it as it will only accept this type of traffic (https) via the proxy server.

So the proxy itself is stopping his machine connecting via the script. His normal internet access is fine and the proxy has the appropriate port opened up to handle port 443 traffic.

All i can think is that maybe the proxy is asking for authentication, however he doesnt know how to enter this into the script.

Is there a way on ISA we can monitor the connection coming in from the client machine or maybe shut off authentication from that specified machine so that it can go straight through? Im new to ISA by the way ;)

Cheers

Yes you can. you can make rule that a client address can use a protocol to a destination.
- client: specify ip address
- protocol: select a protocol pa HTTPS or create a new definition

basic explanation: http://www.microsoft.com/technet/isa/2000/proddocs/isadocs/cmt_accessauthent.mspx?mfr=true

Ok im seeing from the logs that ISA is picking it up as:

cs-username = anonymous
s-operator = CONNECT
cs-status = 407

Which tells me its being blocked because its not authenticating and we have set the general outgoing/incoming requests to block unauthenticated users.

Now as i say im new to ISA. I tried to create a new site & content rule with the destination of the of the site its connecting to and a client set pointing to my machine but this still doesnt work.

Is it possible to bypass authentication for a specific machine on ISA? Or could you advise another way of doing it at all?

cheers.

did you restart isa services after creation of the rule?
ISA2000 needs restart of services when applying changes.

Hi, yeah i did restart the services, but it made no difference, i think this must be a global option only on ISA 2000 :(
