摘要：Methods and systems are provided for improving a firewall implemented at aWLAN infrastructure device (WID). The WID includes a stateful firewall that implements
firewall rules based on an ESSID of the WID to specify whether traffic is allowed to orfrom the ESSID. For example, in one implementation of such a firewall rule, packets thatare required to be sent out on all wired ports can be blocked from being flooded out onWLANs (e.g., the packet is allowed to pass only to the wired ports). A method and systemare provided for preventing a malicious wireless client device (WCD) that is transmittingundesirable traffic from using RF resources by deauthenticating the malicious WCD toremove it from the WLAN and blacklisting it to prevent it from rejoining the WLAN for atime period. Method and systems are also provided for either “on-demand” and/orpredicatively communicating state information regarding an existing firewall session.
