NBG-460N by looking up the IP address of the default gateway for your computer. To
do this in most Windows computers, click Start > Run, enter cmd, and then enter
ipconfig. The IP address of the Default Gateway might be the IP address of the NBG460N (it depends on the network), so enter this IP address in your Internet browser.Set
your device to Router Mode, login (see the Quick Start Guide for instructions) and go to
the Device Information table in the Status screen. Your NBG-460N’s IP address is
available in the Device Information table.
• If the DHCP setting under LAN information is None, your device has a fixed IP
address.
• If the DHCP setting under LAN information is Client, then your device receives an
IP address from a DHCP server on the network.
3 If your NBG-460N is a DHCP client, you can find your IP address from the DHCP
server. This information is only available from the DHCP server which allocates IP
addresses on your network. Find this information directly from the DHCP server or
contact your system administrator for more information.
4 Reset your NBG-460N to change all settings back to their default. This means your
current settings are lost. See Section 26.4 on page 269 in the Troubleshooting for

Port Forwarding
If you have a server (mail or web server for example) on your network,
then use this feature to let people access it from the Internet.
DHCP (Dynamic Host
Configuration Protocol)
Use this feature to have the NBG-460N assign IP addresses, an IP
default gateway and DNS servers to computers on your network.
Dynamic DNS Support
With Dynamic DNS (Domain Name System) support, you can use a
fixed URL, www.zyxel.com for example, with a dynamic IP address. You
must register for this service with a Dynamic DNS service provider.
IP Multicast
IP Multicast is used to send traffic to a specific group of computers. The
NBG-460N supports versions 1 and 2 of IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC 2236).
IP Alias
IP Alias allows you to subdivide a physical network into logical networks
over the same Ethernet interface with the NBG-460N itself as the
gateway for each subnet.
Logging and Tracing
Use packet tracing and logs for troubleshooting. You can send logs from
the NBG-460N to an external syslog server.
PPPoE
PPPoE mimics a dial-up Internet access connection.
PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of
data through a Virtual Private Network (VPN). The NBG-460N supports
one PPTP connection at a time.
Universal Plug and Play
(UPnP)
The NBG-460N can communicate with other UPnP enabled devices in a
network.

Wall-mounting Instructions
Do the following to hang your NBG-460N on a wall.
See the Figure 167 on page 278 for the size of screws to use and how far
apart to place them.
1 Locate a high position on a wall that is free of obstructions. Use a sturdy wall.
2 Drill two holes for the screws. Make sure the distance between the centers of the holes
matches what is listed in the product specifications appendix.
276
NBG-460N User’s Guide
Appendix A Product Specifications and Wall-Mounting Instructions
Be careful to avoid damaging pipes or cables located inside the wall when
drilling holes for the screws.
3 Do not screw the screws all the way into the wall. Leave a small gap of about 0.5 cm
between the heads of the screws and the wall.
4 Make sure the screws are snugly fastened to the wall. They need to hold the weight of
the NBG-460N with the connection cables.
5 Align the holes on the back of the NBG-460N with the screws on the wall. Hang the
NBG-460N on the screws.
