Are you running your own LAN loginserver as well.. or are you trying to use EQEmu's?
If you're running a private one I don't know much about LS issues.. but you can point your server to the EQEmu LS and as long as your ports aren't forwarded or it's locked nobody will be able to connect to your server. Not sure about qserverdb.. I don't even have that in my xml.. Just keep it pointed to your database I'd assume.
Code:
<loginserver>
<host>eqemulator.net</host>
<port>5998</port>
<account>WORLDSERVERUSERNAME</account>
<password>WORLDSERVERPASSWORD</password>
</loginserver>
