Hi Flippinger,
Its good to know that its working in your environment.
You can run the initial network setup by accessing your virtual appliance console as root and running "configure-network" command. It will provide you with the network configuration functions where you should be able to setup proxy, hostname and IP settings as required.
Please note, while setting IP, you will have to make sure you are setting the same IP the support assistant virutal appliance was running prior. If you plan to use a differnt IP for some reason, then you will need to unregister the plugin and then re-register the plugin accessing the registration page from the new updated IP so the plugin has references to the new IP instead of the old one so everything works fine.
Thanks,
