1.1.1 Multi-Gigabit
A 10 Gigabit port supports speed of 10 Gbps if the connected device supports 10 Gbps and a Cat 6a
(up to 100 m) or Cat 6 cable (up to 50 m) is used. The speed drops to 1G if these criteria are not met; it
drops to 100 Mbps if a Cat 5 cable is used (up to 100 m).
If a network device such as a 5G network card, gaming computer, server, Network Attached Storage
(NAS) or Access Point (AP) only supports 2.5 Gigabit or 5 Gigabit connectivity, then the maximum speed
potential of these devices is never reached.
In addition, at the time of writing, most existing cabling is Cat 5e or Cat 6, further limiting maximum
speed or distance potential.
Multi-Gigabit (IEEE 802.3bz) solves these problems by additionally supporting 2.5 Gigabit and 5 Gigabit
Ethernet connections over Cat 5e and higher Ethernet cables. Multi-Gigabit ports are also backward
compatible with 100 Mbps and 1 Gigabit ports.
See the following table for the cables required and distance limitation to attain the corresponding
speed.
1.1.2 IPv6 and IPv6 Firewall
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in
IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. The
NBG7815 can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and support IPv6 rapid
deployment (6RD).
See the LAN chapter in the User’s Guide for information on configuring IPv6 in NBG7815.
Consequently, you can enable and create IPv6 firewall rules to filter IPv6 traffic.
See the Security chapter in the User’s Guide for information on configuring IPv6 firewall in NBG7815.
1.2 Applications for the NBG7815
The NBG7815 supports the following networks.
Internet Access
Connect network devices through the Ethernet ports of the NBG7815 so that they can communicate
with each other and access the Internet.
Table 2 Ethernet Cable Types

Guest WiFi
The NBG7815 allows you to set up a guest WiFi network where users can access the Internet through
NBG7815, but not to other networks connected to it.
USB File Sharing
Share files on a USB memory stick or hard drive connected to your NBG7815 with users on your network.
The NBG7815 also supports file sharing using FTP (file transfer protocol).
The following figure is an overview of the NBG7815’s file server feature. Computers (A) and (B) can
access files on a USB device (C) which is connected to the NBG7815.
Figure 3 File Sharing Overview
USB Media Sharing
The media server feature lets anyone on your network play video, music, and photos from the USB
storage device connected to your NBG7815 without having to copy them to another computer. The
NBG7815 can function as a DLNA-compliant media server, where the NBG7815 streams files to DLNA-
compliant media clients like Windows Media Player.
The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics companies
that works to make products compatible in a home network.
The NBG7815 media server enables you to:
• Publish all share folders for everyone to play media files in the USB storage device connected to the
NBG7815.
• Use hardware-based media clients like the DMA-2500 to play the files.
Note: Anyone on your network can play the media files in the published folders. No user
name and password nor other form of security is required.

Figure 4 Media Server Overview
In the figure above, a USB storage device (A) containing media files is connected to the NBG7815 (B). A
computer (C) with Windows Media Player installed can play the files.
1.3 Operating Modes for the NBG7815
The NBG7815 is set to standard (router) mode by default. The NBG7815 is used to connect the local
network to another network (for example, the Internet). In standard mode NBG7815 has two IP
addresses, a LAN IP address and a WAN IP address. It also has more routing features. In the example
scenario below, NBG7815 connects the local network to the Internet through a modem (M).
Figure 5 Standard Mode Example
Use your NBG7815 as a bridge if you already have a router or gateway on your network. In this mode
your NBG7815 bridges a wired network (LAN) and WiFi in the same subnet. In bridge mode, NBG7815 has
one IP address and NBG7815 interfaces are bridged together in the same network. In the example
scenario below, NBG7815 connects the local network to the Internet through a router (R).

Chapter 1 Introduction
NBG7815 User’s Guide
16
Figure 6 Bridge Mode Example
See the System chapter in the User’s Guide for information on changing the operation mode of your
NBG7815.
1.3.1 Auto-IP Change
When the NBG7815 (A) gets a WAN IP address or a DNS server IP address which is in the same subnet as
the LAN IP address 192.168.123.1, Auto-IP Change allows the NBG7815 to change its LAN IP address to
10.0.0.1 automatically. If the NBG7815’s original LAN IP address is 10.0.0.1 and the WAN IP address is in
the same subnet, such as 10.0.0.3, the NBG7815 switches to use 192.168.123.1 as its LAN IP address.
Figure 7 Auto-IP Change Example
Auto-IP Change only works under the following conditions:
• The NBG7815 must be in standard (router) mode for Auto-IP Change to become active.
• The NBG7815 is set to receive a dynamic WAN IP address.

1.4 Initial Setup Wizard
The wizard appears automatically when the NBG7815 is accessed for the first time or when you reset the
NBG7815 to its default factory settings. The wizard helps you set up the following:
• 2.4G/5G WiFi name and WiFi password
• Automatically check and update your NBG7815 firmware
• Create a myZyxelCloud account to log into the NBG7815
• Authorize the NBG7815 to access your myZyxel Cloud account
• Create a local password as an alternative for logging into the NBG7815
See the Wizard chapter in the User’s Guide for information on running the setup wizard.
1.5 OpenVPN Server/Client
Your NBG7815 supports OpenVPN. OpenVPN is a VPN protocol which is open source and free of charge.
It can be used to create a virtual private network or to interconnect local networks.
It uses OpenSSL encryption library and SSLv3/TLSv1 protocols. This provides high security and anonymity
for all transmitted data.
It also provides faster connection speeds than other VPN protocols.
See the Applications chapter in the User’s Guide for information on creating/configuring an OpenVPN
Server account.
1.6 Ways to Manage the NBG7815
Use the following method to manage the NBG7815.
• Web Configurator. This is recommended for everyday management of the NBG7815 using a
(supported) web browser.
• Zyxel ARMOR mobile app. This is the app you can use to manage the NBG7815 on your cellphone. To
install the app, scan the QR code on the QSG.
1.7 Good Habits for Managing the NBG7815
Do the following things regularly to make the NBG7815 more secure and to manage the NBG7815 more
effectively.
• Change the password. Use a password that is not easy to guess and that consists of different types of
characters, such as numbers and letters.
• Write down the password and put it in a safe place.

Chapter 1 Introduction
NBG7815 User’s Guide
18
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the NBG7815 becomes unstable or even crashes. If you forget your
password, you will have to reset the NBG7815 to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the NBG7815. You could simply
restore your last configuration.
1.8 Resetting the NBG7815
If you forget your password or IP address, or you cannot access the Web Configurator, insert a thin
object into the Reset hole on the NBG7815 to reload the factory-default configuration file. This means
that you will lose all settings that you had previously saved.
1.8.1 How to Use the Reset Button
1Make sure the power LED is on.
2Locate the Reset hole.
3Insert a thin object into the Reset hole for longer than 8 seconds to reset the NBG7815 back to its factory-
default configuration (for example, default Standard (Router) operation mode and login IP address of
192.168.123.1, WiFi SSID and password).
Figure 8 Reset Hole
1.9 WPS Button
Your NBG7815 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure WiFi
network.
WPS allows you to quickly set up a WiFi network with strong security, without having to configure security
settings manually. Each WPS connection works between two devices. Both devices must support WPS
(check each device’s documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to
authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set up
a secure network by themselves.

Chapter 1 Introduction
NBG7815 User’s Guide
