I understand that you are having some issues setting up the Slingbox for Internet Viewing, since you cannot adjust the modem / router settings.
Basically, you need to open the same port on the modem / router, as you did on your first router. The following links will provide you with the step-by-step instructions to follow in order to make the required adjustments. (I assumed that the "netgear wgt264v3" is a typo!)
Let us know how it works for you.
Thanks, that worked. i decided to write this information down so, if i should need this information again I shall know what to do.

Oh, by the way I was correct about the kind of router it does say Netgear wgt624v3 on the back of the router. It is probably an old version.
It is a refurburshed one.
