Go to Section 8.5 on page 146 to view the screen where you can assign the IPTV STB port.

Note: Follow the instructions in the User’s Guide of your STB for hardware connections and setup configurations.

8.3.4 NetBIOS over TCP/IP

NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a computer to connect to and communicate with a LAN. For some dial- up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.

However it may sometimes be necessary to allow NetBIOS packets to pass through to the WAN in order to find a computer on the WAN.

8.3.5 Auto-Bridge

In the rear panel of your NBG-460N, you can see four LAN ports (1 to 4) and one WAN port. The WAN port is for your Internet access connection, and the LAN ports are for your network devices. The WAN port has a different IP address from the LAN ports.

When you enable auto-bridging in your NBG-460N, all five ports (4 LAN ports and the WAN port) share the same IP address as shown in the figure below.

Figure 99 Autobridging Example

IP Address: 192.168.1.20

This might happen if you put the NBG-460N behind a NAT router that assigns it this IP address. When the NBG-460N is in bridge mode, the NBG-460N acts as an AP and all the interfaces (LAN, WAN and WLAN) are bridged. In this mode, your NAT, DHCP server, firewall and bandwidth management (rules) on the NBG-460N are not available. You do not have to reconfigure them if you return to router mode.

Auto-bridging only works under the following conditions:

•The WAN IP must be 192.168.x.y (where x and y must be from zero to nine). If the LAN IP address and the WAN IP address are in the same subnet but x or y is greater than nine, the device operates in router mode (with firewall and bandwidth management available).
