Management Setup
20.1 Introduction
By default, the router may be configured and managed through any
Telnet client or Web browser running on any operating system. There is
no requirement for additional software or utilities. However, for some
specific circumstances, you shall have authority of deciding whether you
would like to allow changing the server port numbers for the built-in
Telnet or HTTP server, creating access control lists to protect the router,
or rejecting the system administrator to login from the Internet. i.e. you
can allow or disallow management from the Internet. For example, a
technician or support person will be able to access the router’s
management menus and adjust any settings or view the router’s status.
The management include the remote management from web and telnet
interfaces. Consequently, it is extremely important to set an admin
password for the router, otherwise your router can be accessed and
seen by anyone in the world. From the menu, you can set the rule to the
router not to reply to pings from the Internet; this offers your router a little
bit extra security because someone is scanning ranges of IP addresses
searching for hosts as your public IP address will then not respond to a
ping request.
