Its not so complicated. I just checked and saw that your router is capable of uPNP (universal plug and play).
Please open your router by typing 192.168.1.1 in your browser, login to your router, and search for the uPNP enabling checkbox, tick it, restart your router.
Now launch azureus and run the configuratiion wizard from the tools menu, at one point you will be prompted to enable uPNP in Azureus which you must do. Now your set !
Your Azureus will "talk" to your router and set the routing path. Just ensure that azureus program access permissions are added to your firewall.
