I would personally use a free dynamic DNS service like the one offered by www.dyndns.com. Sign up for an account which will give you a hostname which attaches itself to your current IP address. Set your server to allow the hostname and hey presto even with a dynamic IP you can have a fully secure connection.

p.s. you will need to use this program on your PC at home to keep the hostname and IP syncronised http://www.dyndns.com/support/clients/
