I read u article on port forwarding in virtualbox but could not see how to add a comment or ask a question. I am using virtualbox 4.0.4 in fedora 14 (the host). I am running xp in virtualbox (the guest). I want to run emule in xp. I have set my router to port-forward to the static ip address in fedora. i tested emule on another computer running xp and the router port-forwarding is working.

Here is my big question? Do i use the same port number for the host and the guest operating system. If not then what port do i list in emule when setting the program if i am using 2 different port numbers? i really struggling to comprehend the situation. thanks
