Si vous avez un routeur Linksys notamant il y a en effet une configuration a faire sur celui-ci.
1. Go to
http://192.168.1.1 in your web browser
2. User name is usually blank, but the password is whatever you set it to be (I believe it is admin by default)
3. Click on the Advanced tab
4. Click on the Forwarding tab
5. At the bottom, there is a button for Port Triggering. Click that to open the port triggering form.
6. On that form, enter whatever you want for Application (I used Ryzom).
7. On that same line, for Trigger Port Range enter 47851 for both of those boxes
8. Again, same line, under the Incoming Port Range enter 1000 and 3000 in those boxes
9. Click Apply, and then close your web browser.
