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
admin# admin security list
Configuration generic parameter
Telnet listening TCP port : 47
