Page 62: What You Should Know
Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the cost of buying extra APs, there is also the possibility of channel interference. The NBG-418N v2’s MBSSID (Multiple Basic Service Set IDentifier) function allows you to use one access point to provide several BSSs simultaneously.

Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG-418N v2 records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the NBG- 418N v2's WAN port receives a response with a specific port number and protocol ("incoming"...

Jane requests a file from the Real Audio server (port 7070). Port 7070 is a “trigger” port and causes the NBG-418N v2 to record Jane’s computer IP address. The NBG-418N v2 associates Jane's computer IP address with the "incoming" port range of 6970-7170.

Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless client can still access the wired network but cannot communicate with each other. NBG-418N v2 User’s Guide...
Page 206 An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. NBG-418N v2 User’s Guide...
Page 207 (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. NBG-418N v2 User’s Guide...
Page 208 RT S/ C T S value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be RT S/ C T S fragmented before they reach size. NBG-418N v2 User’s Guide...
Page 209 Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network. Wireless security methods available on the NBG-418N v2 are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NBG-418N v2 identity.
Page 210 Wi-Fi Protected Access (WPA) WPA2 Most Secure Note: You must enable the same wireless security settings on the NBG-418N v2 and on all wireless clients that you want to associate with it. IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features.
Page 211 MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client. The wireless client ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. NBG-418N v2 User’s Guide...
Page 212 Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a NBG-418N v2 User’s Guide...

Page 214 RADIUS server. "DS" is the distribution system. The AP passes the wireless client's authentication request to the RADIUS server. The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. NBG-418N v2 User’s Guide...
Page 215 PSK and the SSID. The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. NBG-418N v2 User’s Guide...
Page 216 An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN. NBG-418N v2 User’s Guide...
Page 217 For a single AP application, place omni-directional antennas as close to the center of the coverage area as possible. For directional antennas, point the antenna in the direction of the desired coverage area. NBG-418N v2 User’s Guide...
