220.127.116.11. Adding IP Addresses to the Allow and Deny Lists
To add an IP Address to the Allow or Deny list, and begin configuring the IP Security
feature, proceed as follows.
• Both the Allow and Deny list can include Linux operators, wild cards, and
• In some cases, it is not necessary to enter all four "digits" of the IP Address.
For example, if you wish to allow access to all IP addresses that begin with
"192," then you would only need to enter "192."
• The IP Security Configuration menu is only available when the Administrator
Mode is active.
1. Access the IP Security Configuration Menu.
a) Text Interface: Type /N [Enter] to display the Network Configuration Menu.
From the Network Configuration Menu, type 5 [Enter] to display the IP
b) Web Browser Interface: Click on the "IP Security" Link on the left hand side of
the screen to display the IP Security Menu shown.
2. Allow List: Enter the IP Address(es) for the clients that you wish to allow. Note that
if an IP Address is found in the Allow list, the client will be allowed to connect, and
the RSM-8R4 will not check the Deny list.
a) Text Interface: Note the number for the first empty field in the Allow list, then
type that number at the command prompt, press [Enter], and then follow the
instructions in the resulting submenu.
b) Web Browser Interface: Place the cursor in the first empty field in the
parameters menu, then key in the desired IP Address, operators, wild cards,
and/or net/mask pairs.
3. Deny List: Enter the IP Address(es) for the clients that you wish to deny. Note that
if the client’s IP Address is not found in the Deny List, that client will be allowed to
connect. Use the same procedure for entering IP Addresses described in Step 2
18.104.22.168. Linux Operators and Wild Cards
In addition to merely entering a specific IP address or partial IP address in the Allow or
Deny list, you may also use any standard Linux operator or wild card. In most cases,
the only operator used is "EXCEPT" and the only wild card used is "ALL," but more
experienced Linux users may note that other operators and wild cards may also be
This operator creates an exception in either the "allow" list or "deny" list.
For example, if the Allow list includes a line which reads "192. EXCEPT 22.214.171.124,"
then all IP address that begin with "192." will be allowed; except 126.96.36.199
(providing that this address appears in the Deny list.)
