Blocking IE9 -- Kinda???

Comodo Internet Security - CIS Firewall Help - CIS

Hi All,

I am new to CIS having been using another firewall for many years, but have finally seen the light. Comodo is really good, I am impressed.

OK, enough of the pleasantries. I use Firefox as a browser so I have it set as my default browser, but I now have to use IE9 to access some stuff on our network that use an ActiveX app that will only run under IE.

How can I block IE9 from accessing the internet, but still allow it to access a defined path on the network, such as
http://192.168.254.65/then_some_more_stuff_here

I assume I can use CIS to do that, allow Intranet but not Internet. I have searched through all of the Options I can find in the right-click “Open” and did some searching here, but am stumped a little.

Thanks
Harry

Welcome.

You can do this by creating a couple of firewall application rules for IE, the first will allow access to LAN based resources, the second will block everything else.

Application name - IE
Action - Allow
Protocol - TCP
Direction - Out
Source Address - Any
Destination Address - enter here what you need, example 192.168.254.1/255.255.255.0
Source Port - Any
Destination Port - 80 (443)

Application name - IE
Action - Block
Protocol - IP
Direction - Out
Source Address - Any
Destination Address - Any
IP Details - Any

Thanks for the detailed reply. I just went searching in the pages of the right-click and Open, but can’t find anything where I can enter that stuff. It sounds exactly what I need to do but there is nothing that I can find that states, “firewall application rules.” Where will I find that?

Thanks
Harry

Go to Firewall → Network Security Policy → Application Rules.

Click the Add button to add new rules.
