Allow access from ISA to Web - 23.Feb.2007 6:08:16 AM

I am having problems with accessing the web locally from the ISA server (I want to do this to apply MS Updates). Our ISA Servers operate behind a 3rd party managed firewall and I suspect that it may be this that is blocking the access however I have been told it isn't by the Firewall admins.

Is there anything that needs to be configured on an ISA server to allow this access or should it work with the default config?

If there is anything that needs to be configured, what are the basic steps?

Are there any tests that might help identify where the problem is?

Any help greatly appreciated.

Rob

With the default setting, everything is blocked by ISA .

what u need is to create a rule :

Allow > Protocols > From LocalHost > To ( External , or URL Set with the windows Update sites )> Users


OR

u can check System Policy # 17

Allow HTTP/HTTPS requests from ISA Server to specified sites

I have system policy #17 enabled with the MS update sites listed so I guess it must be our external firewall.

Thanks for your help

Cheers

quote:

  Allow > Protocols > From LocalHost > To ( External , or URL Set with the windows Update sites )> Users


if its still now working, then its yes not ISA.
