SSL-DPI Client

I have a TZ570, which interfaces do I need to enable? Just the LAN? Going to implement CFS with our CA root certificate

    @Chechler_2 I guess we're talking about Client DPI-SSL and this has to be enabled on Policy -> DPI-SSL -> Client SSL and in the Zone you like to have the encrypted traffic inspected, e.g. LAN.

    For obvious reasons I would not import the company CA cert, this should be kept away from any device except the CA server. I would go with a Sub CA for DPI-SSL, but you have to distribute this Sub CA to your clients as well, because the Firewall is not able to return the whole certificate chain.

    Thanks again for your quick responses. Certificate statement understood. I still will like to know which interface(s) (WAN, LAN, WIFI, etc) to enable the Deep Packet Inspection.

    Thanks for the link to the article, very helpful. As I mentioned above, I was wondering which Interface(s) (WAN,LAN,WIFI,etc) need to be enabled for the Deep Packet Inspection.
