I forwarded my ports around 4 months ago, actually.
I don't know where the admin page is so... can you tell me where? Remember, its been 4 months since ive forwarded the ports.
OH, OK OK.
The windows version is:
*OPEN WINDOWS EXPLORER*
Type this in address bar: 192.168.1.1
OK, a window will pop up and will ask for "Username", and "Password".
Username: admin (DEFAULT)
Password: admin (DEFAULT), if admin, doesn't work. Try, password. (ALSO DEFAULT FOR DIFFERENT ROUTERS.)
OK, now find a button, or, tab, that says advanced. (Or, if theres another, way. Just, try to find advanced.)
Now, UPnP, should be located around there.
If you see it, click, and enable. SIMPLE.
*BOOM*
