Depends a lot on your infrastructure.

Normally you would use NAT (Network Address Translation) to take an address from your Router / Firewall to a private IP on a server behind that.

Either that or use the public IP assigned to the external interface of your Firewall at the moment.

If you use the existing address you could use PAT (Port Address Translation) to get the requests in.

Yes provided your Firewall allows you to do so.

Nope, nothing needs setting on the server.
