3.15 Management Security

Since you can manage GRT-101 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 from Internet.
There are extra two levels of protection for GRT-101 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 de-
fault TCP port number 23 so that Telnet access to default port number cannot
reach GRT-101. The example below shows you how to setup the Telnet TCP
port number from default 23 to 47:
