When I go to Open ERP.com and sign in, I get a view of my accounts. I click on my company and I get an error. Can I make it reference my local company on port 8069?
You actually CAN do this, I found the answer on this site after frantically searching forever, and although very illusive, it is actually incredibly simple. (I can't post the link cause I don't have karma yet, but thanks to Andreas for posting this originally)
You go to Settings > Paremeters > System Paremeters Edit web.base.url to be whatever URL you want to be in the link to your OpenERP server when emails are sent out in Portal invites, system notification, password resets, etc.
This should really be more obvious, and something that can be set from Company Settings, as I imagine nearly all instances of OpenERP with a public-facing portal start off on a private LAN and need to have this settings changed before going live
