ABSTRACT:
A network system is provided which includes an Enterprise-mode authentication server on a host network, a wireless access point (AP) on a wired local network, and wireless terminals on a wireless local network. The AP obtains a result of user authentication performed by the Enterprise-mode authentication server by monitoring an authentication sequence between the Enterprise-mode authentication server and a wireless terminal that is performing association in a wireless section and obtains information indicating a relationship between a MAC address and an IP address with respect to the wireless terminal by monitoring an ARP table. The AP determines the connection mode of the wireless terminal on the basis of the obtained information and sets a service (e.g., filtering) according to the mode.
