I have a Dell Server with fresh IRedmail server.  Accessing Roundcube and SOGo with SSL (443) works fine.

Dell server has 10.10.50.50 ETH0 and 10.10.50.51 ETH1. Both connected to an office LAN. ETH0 is NATTED(MIP) through firewall with appropriate policies.

Trying to figure out how to avoid SSL exception error when accessing from the same LAN.  I would use https://10.10.50.51 on my browser to access Iredmail server locally, not the https://mail.mycompany.com

The nginx sites-available ssl-default has the catch all for server listening
/etc/nginx/sites-available/00-default-ssl.conf
 
    server {
    listen 443;
    server_name _;

Do I put the 10.10.50.51 ip in the nginx config as one of the server names or is there some config for SSL I need to modify?

thank you!
