WWW Overview
The following figure shows secure and insecure management of the Zyxel Device coming in from the WAN. HTTPS and SSH access are secure. HTTP and FTP management access are not secure.
Secure and Insecure Service Access From the WAN
Service Access Limitations
A service cannot be used to access the Zyxel Device when you have disabled that service in the corresponding screen.
System Timeout
There is a lease timeout for administrators. The Zyxel Device automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling.
Each user is also forced to log in the Zyxel Device for authentication again when the reauthentication time expires.
You can change the timeout settings in the User screens.
HTTPS
You can set the Zyxel Device to use HTTP or HTTPS (HTTPS adds security) for Web Configurator sessions.
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol that enables secure transactions of data by ensuring confidentiality (an unauthorized party cannot read the transferred data), authentication (one party can identify the other party) and data integrity (you know if data has been changed).
It relies upon certificates, public keys, and private keys (see Certificates for more information).
HTTPS on the Zyxel Device is used so that you can securely access the Zyxel Device using the Web Configurator. The SSL protocol specifies that the HTTPS server (the Zyxel Device) must always authenticate itself to the HTTPS client (the computer which requests the HTTPS connection with the Zyxel Device), whereas the HTTPS client only should authenticate itself when the HTTPS server requires it to do so (select Authenticate Client Certificates in the WWW screen). Authenticate Client Certificates is optional and if selected means the HTTPS client must send the Zyxel Device a certificate. You must apply for a certificate for the browser from a CA that is a trusted CA on the Zyxel Device.
Please refer to the following figure.
1 HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the Zyxel Device’s web server.
2 HTTP connection requests from a web browser go to port 80 (by default) on the Zyxel Device’s web server.
HTTP/HTTPS Implementation
If you disable HTTP in the WWW screen, then the Zyxel Device blocks all HTTP connection attempts.Configuring WWW Service Control
Click Configuration > System > WWW to open the WWW screen. Use this screen to specify HTTP or HTTPS settings.

Enable | Select the checkbox to allow or disallow the computer with the IP address that matches the IP address(es) in the Service Control table to access the Zyxel Device Web Configurator using secure HTTPs connections. |
Server Port | The HTTPS server listens on port 443 by default. If you change the HTTPS server port to a different number on the Zyxel Device, for example 8443, then you must notify people who need to access the Zyxel Device Web Configurator to use “https://Zyxel Device IP Address:8443” as the URL. |
Authenticate Client Certificates | Select Authenticate Client Certificates (optional) to require the SSL client to authenticate itself to the Zyxel Device by sending the Zyxel Device a certificate. To do that the SSL client must have a CA-signed certificate from a CA that has been imported as a trusted CA on the Zyxel Device. Click Trusted CAs to go to the Configuration > Object > Certificate > Trusted Certificates screen and check for the trusted certificates settings. |
Server Certificate | Select a certificate the HTTPS server (the Zyxel Device) uses to authenticate itself to the HTTPS client. You must have certificates already configured in the My Certificates screen. |

Avoiding Browser Warning Messages
Here are the main reasons your browser displays warnings about the Zyxel Device’s HTTPS server certificate and what you can do to avoid seeing the warnings:
• The issuing certificate authority of the Zyxel Device’s HTTPS server certificate is not one of the browser’s trusted certificate authorities. The issuing certificate authority of the Zyxel Device's factory default certificate is the Zyxel Device itself since the certificate is a self-signed certificate.
• For the browser to trust a self-signed certificate, import the self-signed certificate into your operating system as a trusted certificate.
• To have the browser trust the certificates issued by a certificate authority, import the certificate authority’s certificate into your operating system as a trusted certificate. Refer to for details.
Enrolling and Importing SSL Client Certificates
The SSL client needs a certificate if Authenticate Client Certificates is selected on the Zyxel Device.
You must have imported at least one trusted CA to the Zyxel Device in order for the Authenticate Client Certificates to be active (see the Certificates chapter for details).
Apply for a certificate from a Certification Authority (CA) that is trusted by the Zyxel Device (see the Zyxel Device’s Trusted Certificates Web Configurator screen).
Trusted Certificates
The CA sends you a package containing the CA’s trusted certificate(s), your personal certificate(s) and a password to install the personal certificate(s).
Installing a Personal Certificate
You need a password in advance. The CA may issue the password or you may have to specify it during the enrollment. Double-click the personal certificate given to you by the CA to produce a screen similar to the one shown next.
1 Click Next to begin the wizard.
2 The file name and path of the certificate you double-clicked should automatically appear in the File name text box. Click Browse if you wish to import a different certificate.
3 Enter the password given to you by the CA.
4 Have the wizard determine where the certificate should be saved on your computer or select Place all certificates in the following store and choose a different location.
5 Click Finish to complete the wizard and begin the import process.
6 You should see the following screen when the certificate is correctly installed on your computer.
Using a Certificate When Accessing the Zyxel Device
To access the Zyxel Device through HTTPS:
1 Enter ‘https://Zyxel Device IP Address/’ in your browser’s web address field.
2 When Authenticate Client Certificates is selected on the Zyxel Device, the following screen asks you to select a personal certificate to send to the Zyxel Device. This screen displays even if you only have a single certificate as in the example.
3 You next see the Web Configurator login screen.
SSH
You can use SSH (Secure SHell) to securely access the Zyxel Device’s command line interface.
SSH is a secure communication protocol that combines authentication and data encryption to provide secure encrypted communication between two hosts over an unsecured network. In the following figure, the computer on the Internet uses SSH to securely connect (SC) to the Zyxel Device for a management session.
SSH Communication Over the WAN Example
How SSH Works
The following figure is an example of how a secure connection is established between two remote hosts using SSH v1.
How SSH v1 Works Example
1 Host Identification
The SSH client (C) sends a connection request to the SSH server (S). The server identifies itself with a host key. The client encrypts a randomly generated session key with the host key and server key and sends the result back to the server.
The client automatically saves any new server public keys. In subsequent connections, the server public key is checked against the saved version on the client computer.
2 Encryption Method
Once the identification is verified, both the client and server must agree on the type of encryption method to use.
3 Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established between the client and the server. The client then sends its authentication information (user name and password) to the server to log in to the server.
SSH Implementation on the Zyxel Device
Your Zyxel Device supports SSH versions 1 and 2 using RSA authentication and four encryption methods (AES, 3DES, Archfour, and Blowfish). The SSH server is implemented on the Zyxel Device for management using port 22 (by default).
Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating system) that is used to connect to the Zyxel Device over SSH.

SNMP
Simple Network Management Protocol is a protocol used for exchanging management information between network devices. Your Zyxel Device supports SNMP agent functionality, which allows a manager station to manage and monitor the Zyxel Device through the network. The Zyxel Device supports SNMP version one (SNMPv1), version two (SNMPv2c), and version three (SNMPv3). The next figure illustrates an SNMP management operation.
SNMP Management Model
An SNMP managed network consists of two main types of component: agents(A) and a manager (M).
An agent is a management software module that resides in a managed device (MD, the Zyxel Device). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
Supported MIBs
The Zyxel Device supports MIB II that is defined in RFC-1213 and RFC-1215. The Zyxel Device also supports private MIBs (ZYXEL-ES-CAPWAP.MIB, ZYXEL-ES-COMMON.MIB, ZYXEL-ES-ZyXELAPMgmt.MIB, ZYXEL-ES-PROWLAN.MIB, ZYXEL-ES-RFMGMT.MIB, ZYXEL-ES-SMI.MIB, and ZYXEL-ES-WIRELESS.MIB) to collect information about CPU and memory usage and VPN total throughput. The focus of the MIBs is to let administrators collect statistical data and monitor status and performance. You can download the Zyxel Device’s MIBs from www.zyxel.com.
SNMP Traps
The Zyxel Device will send traps to the SNMP manager when any one of the following events occurs.
OBJECT LABEL | OBJECT ID | description |
|---|---|---|
linkDown | 1.3.6.1.6.3.1.1.5.3 | This trap is sent when the Ethernet link is down. |
linkUp | 1.3.6.1.6.3.1.1.5.4 | This trap is sent when the Ethernet link is up. |
authenticationFailure | 1.3.6.1.6.3.1.1.5.5 | This trap is sent when an SNMP request comes from non-authenticated hosts. |
