Okay...sorry about not reading that thread.
Okay I followed all of the steps until 5 but it asks me what is my router model. It is BR-6424n of Edimax but it doesn't appear on the list, can I simply use the BR-6504N guide or is it critical?
Also there is something strange, I forwarded 5223,3478,3479,3658 and they are open but port 5223 refuses to be opened, maybe its my firewall?
Also if there is information I should supply then tell me what to cover, I don't want hackers going on my ip address
