Importing Signing CA into Internet explorer or Google Chrome web browser

Hello Experts,

I am setting up a Sophos/Astaro UTM firewall and have enabled HTTPS (SSL) scanning. It appears that I now need to make the firewall a trusted signing authority by downloading the "Signing CA" from the Sophos firewall and then import it into the browser on each machine that will be involved.

I downloaded the signing Certificate from the firewall software and imported it into Internet explorer but HTTPS websites still post the "no certificate error".

** In Internet Explorer I went to Internet Options - Content Tab.
- In Certificates section of Content tab I clicked on Certificates tab
- Clicked Import
- Browsed to/selected file (http_proxy_signing_ca.p12) from my firewall download
- imported this file

When I go to an HTTPS site, I am still getting the certificate errors so it seems the import did not work...

Does anyone know what the exact process is for importing a signing CA into a web browser is?

Thanks!

Did you try to import the Certificate to the computer account?

Open and MMC console -> File -> Add and Remove Snap In-> Certificates-> Add -> Choose Computer Account -> Choose Local Computer -> Ok

Then check if the certificate is stored on a specific store, like personal, trust roots, etc.

Remove it a try to import them again through this MMC.

To import a certificate, right click the folder, all tasks and choose import.
Select the path to the certificate and next.
Choose the store, personal or trusted root or Automatic select the certificate based on the certificate, next and finish.

Then try to open again the browser a see if the problem still remains.

Let us know.

Ok I tried this...

Did this:

Open and MMC console -> File -> Add and Remove Snap In-> Certificates-> Add -> Choose Computer Account -> Choose Local Computer -> Ok

The Certificate is stored on the Console Root. Is this what you mean?

I am a bit unclear on how to import my certificate (exported from my Sophos firewall).

"To import a certificate, right click the folder" What folder are you talking about here? The Console root folder? It does not give me a "browse to" option on the All Tasks context menu.

Still confused here...

Thanks!
