Even though your post is a few days old now, but for anyone else, as well, I am assuming you are wanting outside connections on a private login server.
In your eqemu_config.json file:
Code:
"world" : {
"address" : "149.248.X.X", <----- Your external IP
"local" : "192.168.X.X <------ Your LAN IP
"key" : "60EAQmwxJIL5cfn8Wl6oYCjXGFUVfdZ",
"loginserver" : {
"account" : "",
"host" : "127.0.0.1",
"legacy" : "0",
"password" : "",
"port" : "5998"
