2.13.5 Access Rules
Network access rules restrict access to only those assigned networks or nodes defined. If no
access rules are defined, access will be granted to all networks and nodes.
Note: In order to configure Access Rules, you need ADMINISTRATORrights.
To configure a new, or delete an existing access rule:
1.
Navigate to the MANAGEMENT > Network Setup screen.
2.
In the Actions panel on the left, click on Access Control.
3.
The Network Access Rules window displays:
4.
In the Allow From field, enter a valid IP address. It is not possible, however, to add direct
IP addresses, but instead they must be input as blocks, i.e. you need to add /32 at the
end of an IP address to ensure that only that address is allowed.
Example: 10.2.100.29/32 will allow only 10.2.100.29 access.
I P a d d r e s s n o m e n c l a t u r e :
IPv4—10.10.0.0/16, where 10.10.0.0 is the IP address and 16 is the subnet
mask in prefix form. See the table "Subnet Mask Values" on page53 for a list of subnet
mask values.
IPv6—2001:db8::/48, representing 2001:db8:0:0:0:0:0:0 to 2001:d-
b8:0:ffff:ffff:ffff:ffff:ffff.
5.
Click the Add button in the Action column to add the new rule.
6.
The established rule appears in the Network Access Rules window.
