So this is my problem, I had an access rule wich permit Internet access  from network 10.1.10.0 255.255.255.0

If I configure the settings for the internet explorer proxy it works, I can access Internet, but if I don't configure the proxy settings it doesn't work.

could you help me please.

Thanks for every thing.

Hi Vulatec89,

It sounds like you want to get web access without "proxying" it, is that correct? If so, you should have your PC default gateway as the internal address of the ISA server and ensure the route on it are correct.

Just to add to hornebag


...and ensure the client is able to resolve external DNS names on its own (ensure ISA allows DNS client)

Thanks for your help.

How I can ensure that my ISA allows DNS Client?.

I use the Router IP like gateway in the computers, the router has a default route which send all unrecognized trafic to the ISA server.it is just like to put the internal Address of the ISA as gateway?

Note: I use Internal DNS for the computers in my network.

Who does your client point to for DNS? An internal DNS Server or some external DNS Server?

To test to make sure DNS is making it's way through ISA, verify you have a rule allowing 'DNS Client' from Internal to External.

Go to the ISA console and under Monitoring\Logging, go edit the filter to have an entry like this...

If client point sto External DNS Server
'Client IP Equals %client_ip%'

If client points to Internal DNS Server
'Client IP Equals %DNS_Server_IP%

and start the query

Go to the client and drop to a command prompt and 'ping www.microsoft.com' and watch hte Logging on ISA to see what rule is denying the traffic or allowing it.
