1.5.6 WPS
Your LTE2566-M634 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure WiFi network. WPS is an industry standard specification, defined by the WiFi Alliance.
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). 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.
You can use the LCD of the LTE2566-M634 to activate WPS in order to quickly set up a WiFi network with strong security.

4.5 Configure Data Usage and Statistics

This tutorial shows you how to set up a limited allowance of data.
Dani traveled to a foreign country with her two friends. They purchased a SIM card with a limited data package plan of 15GB that will help them with directions and entertainment during their trip. Dani brought her LTE2566-M634 to share Internet wherever they go during their stay, whilst saving their phone’s battery for pictures and more. They cannot go over the purchased data package plan, because it will result in additional costs for them. To control this Dani can set up a data usage limit in the LTE2566-M634, and notifications that will let them know when they are reaching the limit.
Go to Configuration > Network > Data Usage screen. Click Enable to set up a maximum allowance for data to 1.2GB in the Total allowance field. Set up a notification for when 80% of the limit is reached. Click Apply to save your changes.

7.1.2 What You Need To Know
The information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your LTE2566-M634.
3G
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is optimized as multiple users share the same channel and bandwidth is only allocated to users when they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet access to mobile devices.
4G
4G is the fourth generation of the mobile telecommunications technology and a successor of 3G. Both the WiMAX and Long Term Evolution (LTE) standards are the 4G candidate systems. 4G only supports all­IP-based packet-switched telephony services and is required to offer gigabit speed access.
DNS Server Address Assignment
Chapter 7 WAN
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it.
The LTE2566-M634 can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up.
If your ISP gives you DNS server addresses, manually enter them in the IPv6 DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the LTE2566-M634’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
IPv6 Introduction
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 10 LTE2566-M634 can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and supports IPv6 rapid deployment (6RD).
38
IP addresses. The
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be written as 2001:db8:1a2b:15:0:0:1a2f:0.
LTE2566-M634 User’s Guide
51
Page 52
Chapter 7 WAN
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015, 2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.
IPv6 Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6 prefix length specifies how many most significant bits (start from the left) in the address compose the network address. The prefix length is written as “/x” where x is a number. For example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.
IPv6 Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.

8.1 Overview

This chapter discusses how to configure the wireless network settings in your LTE2566-M634.
The following figure provides an example of a wireless network.
Figure 41 Example of a Wireless Network
CHAPTER 8

WLAN

The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your LTE2566-M634 is the AP.
8.1.1 What You Can Do in this Chapter
• Use the General screen to enable the wireless LAN, enter the SSID and select the wireless security mode (Section 8.2 on page 60).
• Use the Guest AP screen to set up multiple wireless networks on your LTE2566-M634 (Section 8.4 on
page 66).
• Use the MAC Filter screen to deny wireless clients based on their MAC addresses from connecting to the LTE2566-M634 (Section 8.5 on page 67).
• Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 8.6 on
page 68).
• Use the WPS SetUp screen to activate WPS via PBC or PIN configuration (Section 8.7 on page 69).
• Use the WPS Station screen to add a wireless station using WPS (Section 8.8 on page 70).
LTE2566-M634 User’s Guide
58
Page 59
8.1.2 What You Need to Know
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels. Like radio stations or television channels, each wireless network uses a specific channel, or frequency,
to send and receive information.
• Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the
information that is sent in the wireless network.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the wireless network.
SSID
Chapter 8 WLAN
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.
MAC Address Filter
Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters To get the MAC address for each wireless client, see the appropriate User’s Guide or other documentation.
You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network.

; for example, 00A0C5000002 or 00:A0:C5:00:00:02.
WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 4.2 on page 32.

8.2 The General Screen

Use this screen to enable the wireless LAN, enter the SSID and select the wireless security mode.
Note: If you are configuring the LTE2566-M634 from a device connected to the wireless LAN
and you change the LTE2566-M634’s SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your device to match the LTE2566-M634’s new settings.

This displays the operating frequency/channel depending on your particular region.
A standard 20 MHz channel(HT20) offers transfer speeds of up to 144 Mbps (2.4G) or 217 Mbps (5G) whereas a 40 MHz channel(HT40) uses two standard channels and offers speeds of up to 300 Mbps (2.4G) or 450 Mbps (5G). An IEEE 802.11ac-specific 80 MHz channel (HT80) offers speeds of up to 1.3 Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select Auto to allow the LTE2566-M634 to adjust the channel bandwidth automatically.
HT40 (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. A HT80 channel consists of two adjacent 40 MHz channels. The wireless clients must also support HT40 or HT80. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal.
Select HT20 if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding.

10.1 Overview

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network.
The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example).
You assign the LAN IP addresses to the devices (A to D) connected to your LTE2566-M634. The ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D going out to the Internet use the IP address of the LTE2566-M634, which is 192.168.1.1.
Figure 54 NAT Example
CHAPTER 10
NAT
Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the
WAN to be forwarded through the LTE2566-M634.
10.1.1 What You Can Do
• Use the Port Forwarding screen to set a default server and change your LTE2566-M634’s port
forwarding settings to forward incoming service requests to the server(s) on your local network (Section 10.2 on page 76).
• Use the Port Trigger screen to change your LTE2566-M634’s trigger port settings (Section 10.3 on page
78).
• Use the ALG screen to enable or disable SIP (VoIP) ALG (Application Layer Gateway) in the LTE2566-
M634 (Section 10.4 on page 78).

10.1.2 What You Need to Know
Inside/Outside
Inside/outside denotes where a host is located relative to the LTE2566-M634, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/Local
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side.
NAT
In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host.
Chapter 10 NAT
NAT Types
This section discusses the following NAT types that are implemented on the LTE2566-M634.
• Full Cone: In full cone NAT, the NAT router maps all outgoing packets from an internal IP address and
port to a single IP address and port on the external network. The NAT router also maps packets coming to that external IP address and port to the internal IP address and port.
• Address Restricted or Restricted Cone: As in full cone NAT, a restricted cone NAT router maps all
outgoing packets from an internal IP address and port to a single IP address and port on the external network. The difference from full cone NAT is in how the restricted cone NAT router handles packets coming in from the external network.
• Port Restricted: Port restricted cone NAT maps all outgoing packets from an internal IP address and
port to a single IP address and port on the external network.
• Symmetric: The full, restricted and port restricted cone NAT types use the same mapping for an
outgoing packet’s source address regardless of the destination IP address and port. In symmetric NAT, the mapping of an outgoing packet’s source address to a source address in another network is different for each different destination IP address and port.
LTE2566-M634 User’s Guide
75
Page 76
Chapter 10 NAT
The following table summarizes how these NAT types handle outgoing and incoming packets.
Table 28 NAT Types
ADDRESS RESTRICTED
Only external hosts with an IP address to which the internal host has already sent a packet can send packets to the mapped external IP address and port.
PORT RESTRICTED SYMMETRIC
Only external hosts with an IP address and port to which the internal host has already sent a packet can send packets to the mapped external IP address and port.
A host on the external network can only send packets to the specific mapped external IP address and port that the NAT router used in sending a packet to the external host’s IP address and port.
The NAT router maps the internal IP address and port of each outgoing packet to a different external IP address and port for each different destination IP address and port.
Incoming Packets
Outgoing Packets
FULL CONE
Any external host can send packets to the mapped external IP address and port.
The NAT router maps the internal IP address and port of all outgoing packets to a single IP address and port on the external network.

10.2 Port Forwarding

Use this screen to forward incoming service requests to the server(s) on your local network and set a default server. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.
Note: Many residential broadband ISP accounts do not allow you to run any server processes
(such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP.
Port forwarding allows you to define the local servers to which the incoming services will be forwarded. To change your LTE2566-M634’s port forwarding settings, click Configuration > Network > NAT > Port Forwarding. The screen appears as shown.

10.5 Technical Reference

The following section contains additional technical information about the LTE2566-M634 features described in this chapter.
10.5.1 NAT Port Forwarding: Services and Port Numbers
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.
Use the Port Forwarding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.

10.5.2 NAT Port Forwarding Example
Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.
Figure 58 Multiple Servers Behind NAT Example
10.5.3 Trigger Port Forwarding
Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address.
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The LTE2566-M634 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 LTE2566­M634's WAN port receives a response with a specific port number and protocol ("incoming" port), the LTE2566-M634 forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.
10.5.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
LTE2566-M634 User’s Guide

Page 81
Chapter 10 NAT
Figure 59 Trigger Port Forwarding Process: Example
1 Jane requests a file from the Real Audio server (port 7070).
2 Port 7070 is a “trigger” port and causes the LTE2566-M634 to record Jane’s computer IP address. The
LTE2566-M634 associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3 The Real Audio server responds using a port number ranging between 6970-7170.
4 The LTE2566-M634 forwards the traffic to Jane’s computer IP address.
5 Only Jane can connect to the Real Audio server until the connection is closed or times out. The LTE2566-
M634 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol).
10.5.5 Two Points To Remember About Trigger Ports
1 Trigger events only happen on data that is coming from inside the LTE2566-M634 and going to the
outside.
2 If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN cannot trigger it.

11.1 Overview

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the LTE2566-M634’s WLAN as a DHCP server or disable it. When configured as a server, the LTE2566-M634 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.
11.1.1 What You Can Do
• Use the General screen to enable the DHCP server (Section 11.2 on page 82).
• Use the Advanced screen to assign IP addresses on the LAN to specific individual computers based
on their MAC addresses (Section 11.3 on page 84).
• Use the Client List screen to view the current DHCP client information (Section 11.4 on page 84).

13.1 Overview

Use these screens to enable and configure the firewall that protects your LTE2566-M634 and your LAN from unwanted or malicious traffic.
Enable the firewall to protect your LAN devices from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall:
• allows traffic that originates from your LAN devices to go to all of the networks.
• blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic initiated from the WAN is blocked (3 and 4).

13.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
About the LTE2566-M634 Firewall
The LTE2566-M634’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks.
LTE2566-M634 User’s Guide
88
Page 89
Chapter 13 Firewall
It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab under Firewall and then click the Enable check box). The LTE2566­M634's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The LTE2566-M634 can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network.
The LTE2566-M634 is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The LAN (Local Area Network) connects to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.
Guidelines For Enhancing Security With Your Firewall
1 Change the default password via Web Configurator.
2 Think about access control before you connect to the network in any way, including attaching a
modem to the port.
3 Limit who can access your LTE2566-M634.
4 Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a
potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network.
5 For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces.
6 Protect against IP spoofing by making sure the firewall is active.
7 Keep the firewall in a secured (locked) room.

13.3 The ICMP Protection

If an outside user attempts to probe an unsupported port on LTE2566-M634, an ICMP response packet is automatically returned. This allows the outside user to know LTE2566-M634 exists. Use this screen to prevent the ICMP response packet from being sent. This keeps outsiders from discovering your LTE2566­M634 when unsupported ports are probed.

14.1 Overview

This chapter shows you how to configure URL filtering. URL filtering is the ability to block certain web features and specific URLs.
Keyword Blocking URL Checking
The LTE2566-M634 checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking.
The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php
www.zyxel.com.tw
CHAPTER 14

URL Filtering

, the domain name is
.
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
Since the LTE2566-M634 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 LTE2566-M634 would find “tw” in the domain name (www.zyxel.com.tw) the file path (news/pressroom.php
