Unless the network camera explicitly requires it, I would agree, leave UPnP off. If you want it on, then you're have to tell us what exact router you have. There is usually a setting to turn it on or off in the router's admin interface if it's supported ((most do, but not all)). Consult your manual for details.
I'm trying to enable UPnP on my PS3. I have a linksystem router, and a sonicwall TZ180. I have tried them both and can"t get UPnP. I have even hooked strait to the modem (scientific Atlantis 2100 cable modem) and still get the message UPnP unavailable. Any Ideas?
I'm not sure what you are trying to accomplish exactly, perhaps if you explained more fully?
Sonicwalls don't support UPnP. Linksys does, but since you did not say what exact router model you have, it's impossible to say for sure or give directions to activate it. If you are directly connected to the cable modem, there's no UPnP there either.
