I'm not having trouble, just getting more into networking on my own and was reading about port forwarding. I see a typical device to use it would be our cameras. I wonder how D-Link is accomplishing that, I didn't have to do any settings on my router. If I look at my Linksys router in Single Port Forwarding, I don't see anything pre set. I wonder then, how am I accessing my camera's ip via the internet?
