What will happen if "Default forward" is disabled on a RouterOS AP?

Disabling "Default forward" on a RouterOS Access Point (AP) impacts how clients communicate with each other and with the AP itself. When "Default forward" is turned off, clients connected to the AP lose the ability to communicate directly with one another, which means they won't be able to share data or resources directly. This can hinder collaboration and functionality for certain applications.

Additionally, clients may also face challenges connecting to the AP for internet access. This is because the router is set to restrict forwarding of traffic between clients. Although the clients can typically still connect to the AP itself for management or other functionalities, they won't be able to effectively access the internet since the communication pathway is restricted.

In summary, disabling "Default forward" restricts client-to-client traffic, which can lead to confusion about connectivity and limit the overall network functionality, while also potentially complicating clients' access to the internet through the AP. Therefore, both client interconnectivity and potentially their ability to utilize the AP for internet access are affected.
