3.15 Management Security

Since you can manage GRT-101/GRT-401 using Telnet and web browser over the network either from LAN interface or from WAN interface, the management security is important that it prevents invalid access to GRT-101/GRT-401 from Internet. There are extra two levels of protection for GRT-101/GRT-401 Telnet and web servers except login password control:

3.15.1 Telnet port number

You can specify the TCP port number of the Telnet server other than the default TCP port number 23 so that Telnet access to default port number cannot reach GRT-101/GRT-401. The example below shows you how to setup the Telnet TCP port number from default 23 to 47:

admin# admin security port 47

The valid range of the Telnet port number is between 1 and 65534. To show which TCP port number is set to allow access to GRT-101/GRT-401, type
