The wireless networks security can be considered an essential requirement for corporations, enterprises, organizations and governmental institutions. The solution offered by Virtual private network for ” wireless networks applications ” can be considered suitable alternative to the Wired Equivalent Privacy (WEP). This paper addresses this issue and presents a simulated model of ” WLAN ” of IEEE 802.11b standard, secured with fire wall_VPN technology. WLAN model consists of three scenarios which are ” with firewall, without firewall and with fire wall_VPN solution. The OPNET 14.5 modeler used to simulate the WLAN model. The simulation results showed that the firewall and fire wall_VPN solutions act effectively in filtering and tunneling of the specified data traffic. The use of fire wall_VPN solution increases the WLAN delay.
