SpeedTouch™ Remote Access
E-DOC-CTC-20051017-0155 v1.0 90
Hyper-NAT Refinements The SpeedTouch™ features a powerful Hyper-NAT engine allowing the local hosts
to share a single (remotely negotiated) public IP address.
In case Hyper-NAT is enabled on the WAN interface that will be used for remote
management, and a static mapping has been made to allow remote hosts to open a
Telnet session to a host residing on your local network, you must make sure that
Telnet access to the SpeedTouch™ CLI is still possible.
The default port for the Telnet server is set to 23. This can be changed by executing
the following command:
The command above will change the Telnet server port of the SpeedTouch™ from
port 23 (default) to port 50.
For more information on Hyper-NAT, see the SpeedTouch™ Hyper-NAT
Configuration Guide.
