This chapter introduces the main applications of the ZyXEL Device.
1.1 Overview
The NBG-510S Wireless SSL Remote Access Gateway provides wireless connectivity, shared
Internet access, and firewall protection. It also provides easy, secure remote user access for file
sharing and management of home network computers.
Figure 1 Secure Wired and Wireless Internet Access Through Broadband Modem or Router
NBG-510S
• The ZyXEL Device is easy to install and configure.
• Directly connect computers or Ethernet devices to the four-port LAN switch.
• The wireless LAN feature (WLAN) supports IEEE 802.11b and IEEE 802.1g devices as
well as Super G wireless technology for enhanced wireless data throughput speeds.
• NAT and DHCP server features let you share high-speed Internet access through a
broadband modem or router.
• Strong firewall protection secures your network from attacks.
1.1.1 Remote User Access Secured by SSL
The secure remote access portal (user portal) makes it easy to give remote users secure access
to shared files on your home computers. The secure remote access uses SSL (the Secure
Socket Layer protocol), so no security software installation is required. Remote users can use
Internet Explorer or other standard web browsers. Here remote user A uses a web browser to
go to the secure remote access portal and securely access a shared file on a computer behind
the ZyXEL Device.

The secure remote access portal also allows secure remote desktop connections for managing
computers on your network. The secure remote access screens (user portal) includes the
screens the remote users log into and use for secure file sharing and remote computer
management.
1.2 Good Habits for Managing the ZyXEL Device
Use the web configurator for everyday management of the ZyXEL Device with a (supported)
web browser.
Do the following things regularly to make the ZyXEL Device more secure and to manage the
ZyXEL Device 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.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the ZyXEL Device to its
factory default settings. If you backed up an earlier configuration file, you would not have
to totally re-configure the ZyXEL Device. You could simply restore your last
configuration.

6.6 Configuring the Wireless Client
This section describes how to connect the wireless client to a network.
6.6.1 Connecting to a Wireless LAN
The following sections show you how to join a ZyXEL wireless client (not included) to the
wireless network. This example uses the ZyXEL utility that comes with a ZyXEL wireless
client. In the following diagram, the wireless client is labelled C and the access point is
labelled AP.
There are three ways to connect the client to an access point.
52
• Configure nothing and leave the wireless client to automatically scan for and connect to
any available network that has no wireless security configured.
• Manually connect to a network.
• Configure a profile to have the wireless client automatically connect to a specific network
or peer computer.
NBG-510S User’s Guide
Page 53
Chapter 6 Tutorials
This example illustrates how to manually connect your wireless client to an access point (AP)
which is configured for WPA-PSK security and connected to the Internet. Before you connect
to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared
key. In this example, the SSID is “SSID_Example3” and the pre-shared key is
“ThisismyWPA-PSKpre-sharedkey”.
After you install the ZyXEL utility and then insert the wireless client, follow the steps below
to connect to a network using the Site Survey screen.
1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.
2 The wireless client automatically searches for available wireless networks. Click Scan if
you want to search again. If no entry displays in the Available Network List, that means
there is no wireless network available within range. Make sure the AP or peer computer
is turned on or move the wireless client closer to the AP or peer computer.
3 When you try to connect to an AP with security configured, a window will pop up
prompting you to specify the security settings. Enter the pre-shared key and leave the
encryption type at the default setting.
Use the Next button to move on to the next screen. You can use the Back button at any
time to return to the previous screen, or the Exit button to return to the Site Survey
screen.

web site in the address bar. If you are able to access the web site, your wireless
connection is successfully configured.
If you cannot access the web site, try changing the encryption type in the Security Settings screen, check the Troubleshooting section of this User's Guide or contact your
network administrator.
6.6.2 Creating and Using a Profile
A profile lets you automatically connect to the same wireless network every time you use the
wireless client. You can also configure different profiles for different networks, for example if
you connect a notebook computer to wireless networks at home and at work.
This example illustrates how to set up a profile and connect the wireless client to an access
point configured for WPA-PSK security. In this example, the SSID is “SSID_Example3”, the
profile name is “PN_Example3” and the pre-shared key is “ThisismyWPA-PSKpresharedkey”. You have chosen the profile name “PN_Example3”.

CHAPTER 7
Wireless LAN
This chapter discusses how to configure the wireless network settings in your ZyXEL Device.
See Appendix C on page 181 for more detailed information about wireless networks.
7.1 Wireless Network Overview
The following figure provides an example of a wireless network.
Figure 43 Example of a Wireless Network
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 ZyXEL Device is the AP.
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.
NBG-510S User’s Guide
61
Page 62
Chapter 7 Wireless LAN
• 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.
7.2 Wireless Security Overview
The following table shows the relative strengths of common types of wireless security. Use the
strongest security that every wireless client in the wireless network supports.
Table 6 Wireless Security Types
NO RADIUS SERVERRADIUS SERVER
WeakestNo Security
Static WEP
WPA-PSK
StrongestWPA2-PSKWPA2
If you have a RADIUS server, you can use WPA or WPA2 so users have to log into the
wireless network before using it. This is called user authentication. RADIUS servers are more
common in businesses (WPA and WPA2 are also called the enterprise version of WPA).
WPA
If you do not have a RADIUS server, the strongest wireless security you can use is WPA2PSK (WPA2-PSK and WPA-PSK are also known as the personal version of WPA).
"It is recommended that wireless networks use WPA-PSK, WPA, or stronger
security. WEP is better than no security, but it is still possible for unauthorized
devices to figure out the original information pretty quickly.
When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option
(WPA Compatible) to support WPA as well. In this case, if some wireless clients support
WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the
type of wireless network login) and select the WPA Compatible option in the ZyXEL Device.
7.2.1 SSID
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.
62
NBG-510S User’s Guide
Page 63
7.2.2 User Authentication
You can use WPA or WPA2 to have a RADIUS server authenticate users before they can use
the wireless network. You store each user’s user name and password on the RADIUS server.
However, every wireless client in the wireless network has to support IEEE 802.1x to do this.
Unauthorized devices can still see the information that is sent in the wireless network, even if
they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless
users to get a valid user name and password. Then, they can use that user name and password
to use the wireless network.
7.2.3 Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every wireless client in the wireless network must
have the same key.
Chapter 7 Wireless LAN
7.3 Wireless LAN Screen
"If you are configuring the ZyXEL Device from a computer connected to the
wireless LAN and you change the ZyXEL Device’s SSID, channel or security
settings, you will lose your wireless connection when you press Apply to

7.3.2 WEP Encryption
WEP encryption scrambles the data transmitted between the wireless stations and the access
points to keep network communications private. It encrypts unicast and multicast
communications in a network. Both the wireless stations and the access points must use the
same WEP key. Your ZyXEL Device allows you to configure up to four WEP keys but only
one key can be enabled at any one time.
"It is recommended that wireless networks use WPA-PSK, WPA, or stronger
security. WEP is better than no security, but it is still possible for unauthorized
devices to figure out the original information pretty quickly.

CHAPTER 8
WAN
This chapter shows you how to configure the WAN screens on the ZyXEL Device for Internet
access.
8.1 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. The ZyXEL Device can get an
IP address automatically if your ISP gives them out. If you have a static (fixed) IP address
from the ISP, you can manually assign it to the ZyXEL Device’s WAN port.
8.2 DNS Server Addresses
A DNS (Domain Name System) server maps domain names (like www.zyxel.com) to their
corresponding IP addresses (204.217.0.2 in the case of www.zyxel.com). This lets you use
domain names to access web sites without having to know their IP addresses. The ZyXEL
Device can receive the IP address of a DNS server automatically (along with the ZyXEL
Device’s own IP address). You can also manually enter a DNS server IP address in the ZyXEL
Device.
8.3 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
If the Internet Service Provider (ISP) uses your computer’s MAC address in authenticating
your Internet access, have the ZyXEL Device use your computer’s MAC address. Once it is
successfully configured, the address will be copied to the ZyXEL Device’s configuration file.
It will not change unless you change the setting or upload a different configuration file.

8.8 WAN Multicast
Multicast allows packets to be transmitted to multiple hosts. Multicast is an alternative to
unicast packets (packets sent to one computer) and broadcast packets (packets sent to every
computer).
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish
membership in a multicast group - it is not used to carry user data.
When you have multicast enabled, the ZyXEL Device queries all directly connected networks
when it starts up to gather group membership. After that, the ZyXEL Device periodically
updates this information.

CHAPTER 11
NAT and Firewall (WAN to LAN)
This chapter discusses how to configure NAT on the ZyXEL Device.
11.1 NAT Overview
NAT (Network Address Translation - NAT, RFC 1631) changes 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.
11.2 Port Forwarding and Firewall
Incoming sessions (sessions initiated from the WAN and going to the LAN) are blocked by
default. Use port forwarding to allow access from the outside (the Internet) to server(s) on
your LAN.
"Configuring port forwarding also configures the firewall’s WAN to LAN settings.
Port forwarding automatically has the firewall allow unencrypted access from the WAN (the
Internet) to your LAN.
• For secure connections from the Internet to the LAN computers, use the secure remote
user portal (see part VI on page 133).
• To set which services/protocols can access the ZyXEL Device from the WAN (the
Internet), see Section 19.4 on page 129. This allows or disallows remote management of
the ZyXEL Device.
• To control access going from the LAN to the WAN, use the security screens (see part III
on page 91).
A port forwarding set is a list of 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.
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.
NBG-510S User’s Guide
81
Page 82
Chapter 11 NAT and Firewall (WAN to LAN)
"Some 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.
11.2.1 Configuring Servers Behind Port Forwarding Example
The following example shows the IP addresses of computers on the LAN. You can use port
forwarding to send web and FTP traffic to computer A at IP address 192.168.1.33 and Telnet
traffic to computer B at 192.168.1.34. You could make computer C (at 192.168.1.35) the
default. 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 57 Multiple Servers Behind NAT Example
11.3 Port Forwarding Screen
Port forwarding allows traffic from the WAN to be forwarded through the ZyXEL Device. To
change your ZyXEL Device’s port forwarding settings, click Network > NAT > Port Forwarding. The screen appears as shown. Use this screen to define the local servers to which
to forward incoming services.
"If you do not assign a default host, the ZyXEL Device discards all packets
received for ports that are not specified in this screen or remote management.

For example, say you want to allow access for TCP ports 1000 to 2000, but block

and then add another policy (higher in the list) that blocks TCP port 1500.

11.5 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 ZyXEL Device 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 ZyXEL Device's WAN port receives a response with a
specific port number and protocol ("incoming" port), the ZyXEL Device 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.
Chapter 11 NAT and Firewall (WAN to LAN)
11.5.1 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
Figure 60 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 ZyXEL Device to record Jane’s computer IP
address. The ZyXEL Device 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 ZyXEL Device 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 ZyXEL Device times out in three minutes with UDP (User Datagram Protocol),
or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol).
11.5.2 Two Points To Remember About Trigger Ports
1 Trigger events only happen on data that is going coming from inside the ZyXEL Device
and going to the outside.

CHAPTER 13
Access Control
This chapter gives some background information on firewalls and explains how to get started
with the ZyXEL Device’s firewall.
13.1 Access Control Introduction
Access control controls access going from computers on the LAN to the WAN (the Internet).
It also allows you to use QoS to give higher priority to traffic from specific applications (like
voice).
"Configuring access control configures the firewall’s LAN to WAN settings.
Port forwarding automatically has the firewall allow unencrypted access from the WAN (the
Internet) to your LAN.
• For secure connections from the Internet to the LAN computers, use the secure remote
user portal (see part VI on page 133).
• To set which services/protocols can access the ZyXEL Device from the WAN (the
Internet), see Section 19.4 on page 129. This allows or disallows remote management of
the ZyXEL Device.
• To allow unencrypted sessions in from the WAN to the LAN, use the NAT port
forwarding screen (see Section 11.3 on page 82).
13.2 Quality of Service (QoS)
Quality of Service (QoS) prioritizes traffic by application. This helps guarantee the quality of
high priority traffic like voice. QoS refers to both a network's ability to deliver data with
minimum delay, and the networking methods used to provide bandwidth for real-time
multimedia applications. Here are some recommendations for assigning priorities to different
types of traffic.
Figure 65 Priority Assignment Recommendations

MediumInternet and chat since they are somewhat sensitive to delay.
LowE-mail since it is important but can tolerate some delay.
LowestFile transfers (like FTP) since they should not affect other applications and users.
13.3 Firewall Overview
The ZyXEL Device acts as a secure gateway for all data passing between the Internet and the
LAN. The ZyXEL Device 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 ZyXEL Device’s firewall is a stateful inspection firewall. The ZyXEL Device restricts
access by screening data packets against defined access rules. It can also inspect sessions. For
example, traffic from the WAN is not allowed unless it is initiated by a computer in the LAN.
You can configure firewall rules for data passing between interfaces.
The following figure shows the ZyXEL Device’s default firewall rules in action as well as
demonstrates how stateful inspection works. User 1 can initiate a Telnet session from within
the LAN and responses to this request are allowed. However, other Telnet traffic initiated
from the WAN and destined for the LAN is blocked. The firewall allows VPN traffic.
Figure 66 Default Firewall Action
Your customized rules take precedence and override the ZyXEL Device’s default settings. The
ZyXEL Device checks the schedule, source IP address, destination IP address and IP protocol
type of network traffic against the firewall rules (in the order you list them). When the traffic
matches a rule, the ZyXEL Device takes the action specified in the rule.
For example, if you want to allow a specific WAN user from any computer to access
computers behind the ZyXEL Device, you can set up a rule based on the user’s IP address
only. If you also apply a schedule to the firewall rule, the user can only access the network at
the scheduled time.

9:00 AM to Tuesday 5:00 PM. See Section 13.7.1 on page 99 for more examples.
13.7.1 Time Period Examples
Since a time period does not span across days, if you wanted a schedule for off-duty hours on
weekdays, you would need two time periods. One time period covering weekday mornings
(for example Monday to Friday, 12:00 Midnight to 9:00 AM). The other time period covering
weekday evenings (for example Monday to Friday, 9:00 PM to 11:59 PM).
Chapter 13 Access Control
You may need to split into different time periods to have the schedule cover different times on
specific days. For example, say you want to give Internet access to the LAN computers from
6:00 AM to 8:00 AM on all weekdays except Wednesdays. Since the days are not continuos,
you use two different time periods. Add Monday to Tuesday, 6:00 AM to 8:00 AM in time
period 1, and Thursday to Friday, 6:00 AM to 8:00 AM in time period 2.
If you would like to have an overnight schedule like 10:30 PM to 6:00 AM everyday, the time
schedule needs to be broken into two pieces. You may add a Sunday to Saturday from 10:30
PM to 11:59 PM as time period 1, and Sunday to Saturday from 12:00 Midnight to 6:00 AM as
time period 2.
