4.1.1  Logging In Through the Web Management System 
The web management system provides a visualized graphical management interface, which is friendly, easy to 
use, and can achieve efficient configuration and management.   
Configuration Environment Requirements 
The client (PC or mobile terminal) used for logging in to the web management system must meet the following 
environmental requirements: 
  Browser: Google Chrome, Internet Explorer 9.0, Internet Explorer 10.0, Internet Explorer 11.0, and some 
Google/Internet Explorer kernel-based browsers, for example, 360 Security Browser (recommended mode: 
Extreme) are supported. If you log in to the web management system using other browsers, exceptions such 
as garbled characters or formatting errors may occur. 
  Resolution: The recommended resolution specifications are 1024 x 768, 1280 x 1024, 1440 x 960, and 1600 
x 900. If other resolutions are used, the fonts and formats may be out of alignment. 
Key Points 
There are two ways to access the web management system depending on the access interface: 
  LAN access: Access the web management system through the default IP address of the router's LAN port. 
In this case, the management PC must be on the same LAN as the router. 
  WAN access: Access the web management system through the IP address of the router's WAN port. In this 
situation, ensure that the device can access the Internet and the WAN IP is a public IP address. 
 
Note 
  Both LAN access and WAN access require connectivity between the management PC and the router 
interfaces' IP address, that is, the management PC can ping the IP address of the router’s interface. 
  If the router is configured for the first time, you are advised to access the web management system 
through LAN access.

Prerequisites 
Table 4-1 lists the default web configuration of RG-NBR-E series routers. The router starts the web service by 
default, and you can use the default value to log in to the web management system. 
Table 4-1  Default web configurations 
Device IP address 
(management IP address) 
  The default IP address of device LAN0 (Gi0/0) port is 192.168.1.1 
  After the router is configured initially or restores to factory defaults, the 
default management IP address is 192.168.1.1. 
  If HTTPS is enabled, the initial management IP address is 
192.168.1.1:4430.
