I guess you have a Window like the one attached here, except in another language I suppose. The IP required is your computer's LAN IP. It's likely something beginning with "192.168", or maybe "172.16", "172.17"..."172.31", or "10".
Concerning the port numbers, you should put the port numbers as per aMule's configuration, like I said in my previous post. You should put the same numbers in external port and internal port. Don't forget to put the correct protocol (TCP or UDP) ! The first (and main) port is TCP, others are UDP.
