Define trusted CAs for a gateway
Certificate Authorities (CA) verify certificate authenticity with their signatures. Gateways accept certificates only from the trusted CAs that you define.
Before you begin
You must have more than one VPN Certificate Authority element.
By default, the gateways trust all VPN CAs that are currently defined, but you can restrict the trusted CAs. You can also restrict trusted CAs in VPN Profiles.
For VPN Gateways that represent NGFW Engines, you define the trusted CAs in the Engine Editor.
For External VPN Gateways, you define the trusted CAs in the External VPN Gateway Properties dialog box. The system uses the trusted CA definition in the External VPN Gateway element to check that all gateways have the necessary certificates.
