“The problem is I can not control the band and he ends up using all of it to send the information to an external server.”
- You can control the bandwidth of that camera by QoS>(Adding to QoS group staff or guest). Then set the applicable up/down bandwidth limit under “Individual Bandwidth Control”.
"Nor can I know which ports it uses."
2. To see which ports the camera is using you can check by Status>Active Sessions>Search: Define the applicable IP address. You will be able to see what the source/destination ports are.
NAT Mapping will forward all ports over the specified Public IP to that specific device (To set specific ports, use port forward rules to lock down specific ports inbound to the camera).
Outbound Policy rules will let you control how you would like traffic routed from the camera out to the external server. In your case I would use Source IP or Mac Address of the camera. If by source ip, ensure you have created a DCHP reservation for that device. Typically for this type of service you will want to use the priority algorithm which will force this stream out through a specific WAN and the subsequent WANs on the list will be used for fail-over purposes.
