Port Renumbering
Settings
If you use NAT pinholes to forward HTTP or Telnet traffic through
your Cayman 2E-W to an internal host, you must change the port
numbers the Cayman 2E-W uses for its own configuration traffic. For
example, if you set up a NAT pinhole to forward network traffic on
Port 80 (HTTP) to another host, you would have to tell the Cayman
2E-W to listen for configuration connection requests on a port
number other than 80, such as 6080.
After you have changed the port numbers the Cayman 2E-W uses for
its configuration traffic, you must use those port numbers instead of
the standard numbers when configuring the Cayman 2E-W. For
example, if you move the router's Web service to port 6080 on a box
with a DNS name of superbox, you would enter the URL
http://superbox:6080 in a Web browser to open the Cayman 2E-W
graphical user interface. Similarly, you would have to configure your
Telnet application to use the appropriate port when opening a
configuration connection to your Cayman 2E-W.
set servers web-http [ 0 - 32767 ]
Specifies the port number for HTTP (web) communication with the
Cayman 2E-W. Because port numbers in the range 0-1024 are used
by other protocols, you should use numbers in the range 2000-32767
when assigning new port numbers to the Cayman 2E-W web
configuration interface.
set servers telnet-tcp [ 0 - 32767 ]
Specifies the port number for Telnet (CLI) communication with the
Cayman 2E-W. Because port numbers in the range 0-1024 are used
by other protocols, you should use numbers in the range 2000-32767
when assigning new port numbers to the Cayman 2E-W Telnet
configuration interface.
SNMP Settings
The Simple Network Management Protocol (SNMP) lets a network
administrator monitor problems on a network by retrieving settings
on remote network devices. The network administrator typically
runs an SNMP management station program on a local host to obtain
information from an SNMP agent such as the Cayman 2E-W.
