Wireless Client Isolation is a feature for the SMC2586W-G in AP or Bridge
Master mode to block wireless-to-wireless traffic between STAs so that the
STAs cannot see each other. This feature is useful for WLANs deployed in
public places. This way, hackers have no chance to attack other wireless
users in a hotspot.
When the Wireless client isolation setting is set to wireless clients (STAs)
associated to this SMC2586W-G, which acts as an AP, cannot see each other,
and wireless-to-wireless traffic between the STAs is blocked.
When the setting is set to All APs in This Subnet, traffic among wireless
users of different SMC2586W-Gs in the same IP subnet is blocked. The
behaviors are illustrated in the following figures.
Fig. 46 Behavior of the "This AP Only" wireless client isolation option.
