My router cannot ping an IP-Camera attached to a switch. Therefore I cannot reach this IP-Camera from over the internet using port forwarding.
Other PCs can ping the IP-Camera within the network. The router cannot.
The IP-Camera is connected to the switch. The switch is connected to the router.
(I have another switch but disconnect it when doing any testing/changes)
I have tried connecting the IP-Camera directly to the router and it pings successfully.
