How to install a wildcard certificate without generating a CSR from each gateway

[AaronPW]

Hello. 

I'm trying to use a 3rd party wildcard certificate for GAIA portal access to some of our firewalls.  A CP engineer and I installed wildcard.key file as server.key and the .crt file as server.crt but the IP was still resolving to the ISP domain name so it was giving a domain mismatch error. 

I got that fixed and now the ip resolves to our domain but the website still shows an error and says that the domains do not match. 

I got a new engineer who says we have to do a CSR for each gateway and cannot use the wildcard certificate. 

Is this the case or were we just not communicating?

As far as I know, this is supported.
Are you accessing the Gaia WebUI by FQDN?

Im fairly positive you can use wildcard cert, had seen customers do it before.

Do you use a IP-address for the gateway? That's not possible. The wildcard just includes domains. There is not wildcard IP-address certificate. You have to use FQDN.
