Problems with accessing websites through IronPort S370

I have a new IronPort S370 set up in explicit forward (proxy) mode.


The system is set up to use NTLM authentication, has an account on the domain, and is able to see users, groups, etc. in the domain. It tests out correctly.


So I built a new access policy that uses the domain realm and placed this policy above the default global policy on the IronPort. I associated a URL filtering policy with it, and put in a handful of websites to test. However, I am running into issues.


When I access some sites, I can get to them. When I access a site like, I get a message that I have to log in (page cannot be displayed).


Looking at the logs, it looks like the IronPort is tunneling all the http traffic, and that 443 is hitting


Is this correct? Whan can I do to change/fix this?

OK, I have some more info for

OK, I have some more info for this.


The problem seems to be that the Global Access Policy overrides a specific policy I create.


If I create a group, use domain authentication (realm), assign a custom URL category to this group within an access policy (permitting access to certain URLs), and within the global policy block all categories by default, everything gets blocked.


In policy trace, I see the user is found in the directory, the website IP resolves, but the access policy I created is never looked at: only the global policy.


Is there something I am missing here?


After you add URL categories

After you add URL categories in your new access Policy and submit it, click link in URL Filtering column for your new access policy just created to edit it.

Click Select all link in Monitor column. Click submit.

Otherwise it will inherit global settings.
