I have a router that shares internet between a computer and a server (server then gives me internet) now i can use remote desktop to do stuff to my server, but i cant get the other computer to connect to the server though remote desktop. will there be something in my router that will allow me to do this. I am using a belkin g+ mimo router.
the network setup is,
router---dads computer (wifi)
router---my server (wifi)
server--- my computer (cable)

Thanks For The Help
