I'm planning to buy a SSL certificate from a CA provider on the internet. During a certificate generation process, the wizard ask me to enter "COMMON NAME".
Can you tell me what is this common name? what name should I type here?
My network structure is like this:
In my local lan, I have one mail server and client access the internet through
the internet gateway/router. client connects to the office mail server from the internet through a public IP. and the router will redirect to the local mail server.
Now I want to install a SSL certificate on this mail server. So I wonder what name should I use for the common name? should I key in the mail server's local ip or local netbios name or the public IP or the public DNS name?
Now I'm confuse with all this things.
So please guide me on this.
