My slingbox M1 works great except when I want to connect at work. Slingplayer says it cannot connect to my Slingbox. I can connect at work using the desktop player and on my iphone when I am on 3G. I can connect to my home network when I am on other outside Wifii networks, but not my office Wifi. I have a pretty good firewall at my office using a Watchguard XTM. Does anyone know how to configure wireless user to be able to access Slingbox?
Most work networks have high security/firewall that can prevent the Slingbox from connecting. I would like for you to take a look at this article linked below, it could further explain what is happening and how you could fix it:
Hope this helps!
