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?
