Local Host cannot access the Internet after few days - 15.Apr.2006 5:31:07 AM

Hello all,
I am installed ISA 2004, and everything went OK so far. I got the VPN Portion up and running as well as the web caching. everything seem to be working fine.
I do have one problem which is,
After a few days ISA server was not able to access the internet, however I created a rule as the following
Action: Allow
Protocols: All Outbound traffic
From: Local Host
To: External

I was able to access the internet from the ISA Server when I created the rule, but after a few days I was not able to do that. That, of course, effected the Web caching sessions and the windows update checking.

What is causing this problem and how can solve it?
Thanks
Hisham

Hi Hisham,

Why are you connecting to the Internet from the local host? That exposes you to exploits and is not a firewall best practice.

Hi Tom,
I dont want to keep the local host from getting microsoft update and antivirus updates. I figured out what mistake I was doing. I did not point IE to use the proxy on the local host.
As soon as I typed the local host ip addres and the port in the proxy in IE, everything worked fine.
Do you recommend to just isolate ISA Server from accessing the internet?
Thanks
Hisham

You should maintain internal WSUS and Virus update servers and update from them.
