You can use such services as no-ip.com or dyndns.org to create a DNS A-record for your home external IP-address. This DNS record will be resolved everywhere. Also you can modify the 'hosts' file on your work computer (/etc/hosts in Linux and c:\windows]system32\drivers\etc\hosts in windows) and put the name of your home computer there. With second approach you'll be able to resolve the name on your work computer only.
