Hi, Meraki MX60 is a router.

EAP wifi clients are connected to the WAN side of the router, while the video stream are connected in the LAN side.

Routers are usually configured with firewalls. By default, to prevent unauthorized access to the internal network (LAN) from the external network (WAN), access from the WAN port to the LAN port is blocked. This is a basic security strategy to protect the devices connected to the LAN from potential attacks from the Internet (WAN). For example, most home routers have state - inspection firewalls that examine the state of data packets. For connection requests from the WAN to the LAN, they are judged according to pre - set rules. If there is no explicit permission rule, these requests will be rejected.

In addition, NAT is an important function of routers. It is used to convert the private IP addresses in the LAN to the public IP address of the WAN port, enabling the devices in the LAN to access the Internet. However, NAT is mainly designed for communication from the LAN to the WAN, not the other way around. Accessing the LAN from the WAN goes against the basic design intention of NAT because it would expose the internal network to external risks. For example, in a typical dynamic NAT or Port - Address Translation (PAT) configuration, the router does not automatically allow reverse access from the WAN to the LAN.

The easiest solution is: plug the EAP units in the LAN side of the video streams so that they are all in the same LAN 192.168.0.40/24.
