Inside Sling Box TV Streaming

Trying set up Wireless Webcam – what port – how do i get Windows to install it automatically?

i am looking to have it available remotely from work - i already have my slingbox through port 5001 - can i also have the web cam or is it one device at a time? I got windows to recognize it hard wired with Ethernet, but when i got to wireless, it wont connect - what port ? It is a 2Wire DSL modem -
sorry for the rambling!
I have a wireless webcam that I want to set up at home and remotely access it from work - I want my PC / firewall to allow access to it, but it doesnt - What port should it be set to? If I have my Slingbox set up at home for me to watch at work as well - can i ideally have the slingbox and the webcam streaming to me at work?
