Trouble with loggins from internet

[tajjej]

I have two computers that are able to log into the server I created. They log in OK from the LAN side (through the internet, in other words, they log in via: [LoginServer]
Host=eqemulator.net:599

But when someone tries to log in from outside (via the internet) They can only get as far as making a character. When they try to enter the game, it fails.

I fixed the "Error 1017" by forwarding TCP ports 5998 & 9080 and UDP port 9000. I am guessing I need to forward another port or two.

Can anyone tell me what ports need to be forwarded? Or another possible fix for this?

Thanks in advance,
