You can create as many subdomains as you like on your dns server - you don't have to register them... it's free as long as you own the domain. You just add a host (A) record on your dns named for example server and that server's external IP (check your dns file and just add a similar entry) and then your dns server will be able to translate this entry to server.domain.com - that's all...

You should configure your firewall with a NAT translation rule so that server is accessible from the outside world with it's internal IP address. Just check NAT entries on your firewall for other entries and add a similar one for your new server...
