HAPTER 10.1 Overview This chapter discusses the NBG5715’s WAN screens. Use these screens to configure your NBG5715 for Internet access. A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.
Page 68 (and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the NBG5715, which makes it accessible from an outside network. It is used by the NBG5715 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG5715 tries to access the Internet.
Page 69: Multicast
A and D. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group - it is not used to carry user data. The NBG5715 supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2).

Page 107: Trigger Port Forwarding
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG5715 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 NBG5715's WAN port receives a response with a specific port number and protocol ("incoming"...
Page 108: Two Points To Remember About Trigger Ports
Chapter 14 NAT 14.5.5 Two Points To Remember About Trigger Ports Trigger events only happen on data that is going coming from inside the NBG5715 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.

Key management allows you to determine whether to use IKE (ISAKMP) or manual key configuration in order to set up a VPN. 18.7.2 Encapsulation The two modes of operation for IPSec VPNs are Transport mode and Tunnel mode. At the time of writing, the NBG5715 supports Tunnel mode only. NBG5715 User’s Guide...
Page 137: Ike Phases
There are two phases to every IKE (Internet Key Exchange) negotiation – phase 1 (Authentication) and phase 2 (Key Exchange). A phase 1 exchange establishes an IKE SA and the second one uses that SA to negotiate SAs for IPSec. NBG5715 User’s Guide...
Page 138: Negotiation Mode
• Set the IPSec SA lifetime. This field allows you to determine how long the IPSec SA should stay up before it times out. The NBG5715 automatically renegotiates the IPSec SA if there is traffic when the IPSec SA lifetime period expires. If an IPSec SA times out, then the IPSec router must renegotiate the SA the next time someone attempts to send traffic.
Page 139: Ipsec And Nat
18.7.5 IPSec and NAT Read this section if you are running IPSec on a host computer behind the NBG5715. NAT is incompatible with the AH protocol in both Transport and Tunnel mode. An IPSec VPN using the AH protocol digitally signs the outbound packet, both data payload and headers, with a hash value appended to the packet.

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. NBG5715 User’s Guide...
Page 224 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. NBG5715 User’s Guide...
Page 225 (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. NBG5715 User’s Guide...
Page 226 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. NBG5715 User’s Guide...
Page 227 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 NBG5715 are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NBG5715 identity.
Page 228 Wi-Fi Protected Access (WPA) WPA2 Most Secure Note: You must enable the same wireless security settings on the NBG5715 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 229 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. NBG5715 User’s Guide...
Page 230 The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. NBG5715 User’s Guide...

Page 232 WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it. NBG5715 User’s Guide...
Page 233 The AP checks each wireless client's password and allows it to join the network only if the password matches. The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. NBG5715 User’s Guide...
