Chapter 8 LAN Figure 69 LAN and WAN IP Addresses The LAN parameters of the NBG-418N v2 are preset in the factory with the following values: • IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits) • DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.

TCP/IP configuration at start-up from a server. You can configure the NBG-418N v2’s LAN as a DHCP server or disable it. When configured as a server, the NBG-418N v2 provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else the computer must be manually configured.

Page 111: Nat Port Forwarding Example
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).
Page 112: Two Points To Remember About Trigger Ports
TCP/IP (Transfer Control Protocol/Internet Protocol). 10.6.5 Two Points To Remember About Trigger Ports Trigger events only happen on data that is coming from inside the NBG-418N v2 and going to the outside. If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it.

The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php. Since the NBG-418N v2 checks the URL’s domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/ pressroom.php, the NBG-418N v2 would find “tw”...

For example, if the keyword "bad" was enabled, all sites containing this keyword in the domain name or IP address will be blocked, e.g., URL http:/ /www.website.com/bad.html would be blocked.

Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client A and B can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other. NBG-418N v2 User’s Guide...
Page 204 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 205 (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 206 If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. NBG-418N v2 User’s Guide...
Page 207 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 208 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 209 For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. NBG-418N v2 User’s Guide...
Page 210 The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or re-authentication times out. A new WEP key is generated each time re-authentication is performed. NBG-418N v2 User’s Guide...
