Welcome to Firewalls.com.
In this video you are going to learn how to properly setup the Internet Explorer browser to use the SonicWALL DPI-SSL service to avoid certificate errors.
Once the DPI-SSL service is configured and running on your SonicWALL firewall, users trying to access secure web sites through the firewall will get certificates warnings from Internet Explorer telling them that the server certificate was issued by an untrusted CA.
This happens because the DPI-SSL service creates on-the-fly web server certificates and signs them with its own CA certificate that IE does not trust.
