WOTLK server working for public players but LAN players cant connect

the title states pretty much all I know; anyone outside my private host network has no problem joining but anyone trying to connect from LAN gets an unable to connect error.

I’ve tried opening a new server in the data table that uses my private IP but i get a server error stating Client requested connecting with realm id 2 but this realm has id 1 set in config

It is not a firewall issue

so after two days of trying to figure this out I realized its currently impossible to fix if you have an ISP that disables loopback, so devs if you are reading this make a way to send a LAN address to a WAN server

read readme 1st, there you have how to setup.
