Matrix ETERNITY NE - Call Restriction Based on IP Address

Matrix ETERNITY NE System Manual 443
Call Restriction based on IP Address
What's this?
When the WAN port of ETERNITY NE is connected to a public IP network, it is may be necessary to restrict traffic
to and from a particular IP address only.
With the feature 'Call Restriction based on IP Address', ETERNITY makes it possible to entertain requests on its
WAN port for predefined IP Addresses only,
How it works
For this feature to work,
• the IP Address based call traffic restriction flag must be enabled.
• the "White List IP Address" list, i.e. a list of IP Addresses and their respective Subnet Masks from where
the traffic is to be allowed, must be configured.
• With flag enabled and the table configured, traffic coming from all IP Addresses, other than those
programmed in the White List, will be blocked.
• If the flag "IP Address based call traffic restriction" is enabled, but the White List IP Address Table is
blank, all incoming traffic will be rejected and it will not be possible to make VoIP calls to ETERNTY NE.
• Call Restriction will be applied also on all the SIP Trunks.
How to configure
• Create a White List Table. Make a three column table on a sheet of paper.
Make a list of IP Addresses from which you want to allow traffic. You are allowed to program a maximum of
5 IP Addresses. For each IP Address enter the corresponding Subnet Mask.
• With the White List Tables ready, follow these steps:
• Open Jeeves.
• Log in as System Engineer.
