Basic Configuration
4. If the client’s IP Address is not found in the Deny list, the client will be allowed to
connect, even if the address was not found in the Allow list.
Notes:
• If the MPC finds an IP Address in the Allow list, it will not check the Deny list,
and will allow the client to connect.
• If both the Allow and Deny lists are left blank, then the IP Security feature will
be disabled, and all IP Addresses will be allowed to connect (providing that
the proper password and/or SSH key is supplied.)
• When the Allow and Deny lists are defined, the user is only allowed to specify
the Client List; the Daemon List and Shell Command cannot be defined.
5.9.3.1. 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.
Notes:
• Both the Allow and Deny list can include Linux operators, wild cards, and
net/mask pairs.
• 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
Security Menu.
b) Web Browser Interface: Place the cursor over the "Network Configuration"
link on the left hand side of the screen. When the fly-out menu appears, click
on the "IP Security" Link to display the IP Security Menu.
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 MPC 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
above.
