6.3.4.1 Disabling Protocols
Using the Remote Power Switch's Firewall feature, you can block access to the unit from certain
protocols by blocking all IP addresses on the port on which the protocol operates. To disable access in
this manner, the AB6 must operate in
Black List Mode.
To block all all IP addresses on a particular port:
1. Click the Block all enabled entries radio button.
2. On an open Firewall Entry , change both of the Ports fields to the port number of the protocol you
wish to disable
·
i.e. for HTTP, set both port fields to 80. (HTTP operates on port 80)
· for Telnet, block port 2002
·
for HTTPS, block port 443
3. Change both the Network / Mask fields to 0.0.0.0 . This tells the the AB6 to block all IP addresses on
the specified port.
4. Set the protocol to TCP
Note: Make sure you block only the ports associated with the protocol you wish to disable. Leaving the
Ports fields unaltered while setting the Network and Mask fields to 0.0.0.0 will block all IP access to
the unit (blocking all IP addresses on all ports).
You can block SNMP (default, port 162) or DCP (default, 2001) protocols in this manner, however, you
can also disable those features entirely from the SNMP and System tabs respectively.
