If you use a mail forwarding service, you change your address on everything to the address given to you. All mail is sent to your mail forwarding service. The service then sends your mail to you when you request it and at an address specified by you. This is the type of service that many full-timers use. If you are needing this for only 6 months, I don't think I would use mail fowarding as you actually have to change your address on everything. The postal service premium may cost, but it's probably the best way to get all of your mail.
