The functionality of the website for http://watch.slingbox.com is very dependant on your browser's user agent information. If you're using software to spoof the user agent of another browser then I would recommend to toggle it back to default.
You can see your current browser's user agent by going to (http://whatsmyuseragent.com). On my Windows XP box with Firefox 3.3.6 which works with the Slingplayer web client this is what my user-agent string looks like "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:188.8.131.52) Gecko/20100625 Firefox/3.6.6".
The information provided looks exactly like yours with the exception of the forwarding message. See below
Your User Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:184.108.40.206) Gecko/20100625 Firefox/3.6.6
Your IP Address: 220.127.116.11

Is there something else I need to review???
As a work around you can download the Slingplayer Desktop (http://support.slingbox.com/go/downloads).
Hi jpsoc722, Efrez has given you a good suggestion but you can always try this on the web player:
