I've been beating my head over this all day...

I have my server setup and working - local connection works fine, connecting from the other computers on my lan works fine - but connecting from the internet does not. The server does pick up on the incoming connection, but what happens on the client's end is that the client freezes on the "Verifying account" screen. There is no problem with the account (at least I'm fairly sure, heh).. these have been tested and work fine when connecting locally or through the lan... ports and server addresses should be fine for the same reason, and also because the clients do connect.. only they hang on the verification...

The only clue that something is amiss is the following msg that appears when the client connects:

Undefined message type 84
Unexpected message type 84, 62 bytes (IP:####, Account:None)

Does anyone have an idea what might be the problem?

Edit:
Before anyone asks, I have already forwarded the port through my router!

What address clients uses for connect from outside of LAN?
Show content of config\servers.cfg.

What client are you trying to connect with ?
What version of client ?
How are you removing the encryption ( Razor, UORice, UOCh ) ?

Undefined message type 84
Unexpected message type 84, 62 bytes (IP:####, Account:None)

Because that looks like there should still be some encryption in the client.
Normally the logon packet is 0x80 but your client is sending 0x84 for some reason...

check your Listener what the encryption is set on, should be ignition, uorice or none.

Thanks for the tip!

It was in fact the encryption settings that were holding things up.

Everything working properly now.
