What is the prescribed method for removing alerts for pages served by proxy?
Most clients will utilize the Certificate Authority that comes with the system by default.
A few organizations may as of now have a Certificate Authority that they are utilizing that has produced certificates for their internal PCs and deployed on their clients. One example would be from Active Directory Certificate Services. Another example would be from a previous web proxy. To use CA, you can install it on the firewall and use it inside the web proxy. As opposed to utilizing your root Certificate Authority, you may rather need to make a middle of the intermediate Certificate Authority and use that. You will in any case have to introduce the root Certificate Authority (without private key) so the web proxy can build the complete certificate chain.
From WebAdmin, you can download a copy of the Certificate Authority that you can deploy to all clients using Active Directory. If it's not too much trouble, note that Windows/Internet Explorer and Chrome utilize a similar Certificate Authority store, nonetheless, FireFox has its own different store.
If you have different firewalls, you might need to make a Certificate Authority separate from a firewall, and afterward install and use it on all firewalls.
To utilize a declaration on the actual firewall that is produced from the Certificate Authority, it is simpler to do this beginning with a Certificate Authority that is discrete from the firewall and afterward introducing it.
