Nightspire, yes..what they said!
I completely misunderstood your intended server configuration and I apologize for taking you down the 'Rabbit Hole.' (This is why I recommended using only one thread
)
The instructions I gave are for setting up a private LAN setup, or with port forwarding, a server with LAN and WAN clients.
Disregarding everything that I said to change, getting your configuration back to original state is best, with any changes others have recommended. (I have zero experience with eqemulator.net login servers and will not speak on such..again, my bad)
Once your server is back up and running the way it was before, if you're still having trouble with internet clients please repost your original problem, along with what client types are being used.
