Accessing the router configuration pages remotely
To access the router's configuration pages remotely:
1 Open a new browser window and navigate to the WAN IP address and assigned port number of the router,
for example
http://123.209.130.249:8080
Note – You can find the router's WAN IP address by clicking on the "Status" menu. The WWAN IP field in the WWAN
Connection Status section shows the router's WAN IP address.
2 Enter the username and password to login to the router and click Log in.
Note – To perform functions like Firmware upgrade, device configuration backup and to restore and reset the router
to factory defaults, you must be logged in with the root manager account.

Server certificate

What is HTTP Secure?
HTTP Secure or HTTPS is the use of the HTTP protocol over an SSL/TLS protocol. It is used primarily to protect
against eavesdropping of communication between a web browser and the web site to which it is connected. This is
especially important when you wish to have a secure connection over a public network such as the internet. HTTPS
connections are secured through the use of certificates issued by trusted certificate authorities such as VeriSign.
When a web browser makes a connection attempt to a secured web site, a digital certificate is sent to the browser
so that it can verify the authenticity of the site using a built-in list of trusted certificate authorities.
There are two main differences between how HTTPS and HTTP connections work:
HTTPS uses port 443 while HTTP uses port 80 by default.
Over an HTTPS connection, all data sent and received is encrypted with SSL while over an HTTP connection,
all data is sent unencrypted.
The encryption is achieved through the use of a pair of public and private keys on both sides of the connection. In
cryptography, a key refers to a numerical value used by an algorithm to alter information (encrypt it), making the
information secure and visible only to those who have the corresponding key to recover (decrypt) the information.
The public key is used to encrypt information and can be distributed freely. The private key is used to decrypt
information and must be secret by its owner.
Each NTC-220 series router contains a self-signed digital certificate which is identical on all NTC-220 series routers.
For a greater level of security, the router also supports generating your own unique key. Additionally, you may use
third party software to generate your own self-signed digital certificate or purchase a signed certificate from a
trusted certificate authority and then upload those certificates to the router.
Generating your own self-signed certificate
To generate your own self-signed certificate:
1 Click the System item from the top menu bar, then Administration from the side menu bar and then Server
certificate.
2 Select a Server key size. A larger key size takes longer to generate but provides better security.
3 Click the Generate button to begin generating Diffie-Hellman parameters.
