Background: I have a number of DLINK cams. ALL cams have the latest firmware. Due to a bad modem, had to swap it out for a new one. Modem and router are working fine following the change.
I had UPNP disabled on router and could access the cams remotely via the mydlink app prior to the modem swap. However, post modem swap, I cannot access the cams remotely but they work locally fine.
I believe the issue is due to UPNP being off. My question is what are the desired settings for UPNP in order for the cams to work remotely? I think the answer is:
1) Enable UPNP in router
2) Enable UPNP for each cam by logging into its settings
Anything else? http://support.dlink.com/emulators/dcs930l/100/helpadva.htm What about UPNP port fowarding setting on the cam???
I read something about multicasting? Is that relevant? Can you explain it?
