No doubt you have found the answer to this, but if not its a simple trip to wordpress admin, log in go to options and change the wordpress URL and blog address URL to that of your servers IP e.g. https://192.176.0.45:8888/sitename. The only downside to doing it this way is if you use dhcp, becuase you will only be able to log on when that machine is allocated the specific IP you enetered in the options. To avoid this just make sure you fix the IP of your test server
