White List IP Address
When the Ethernet WAN port of NAVAN is connected to a public IP network, it is may be necessary to allow traffic
from specific IP addresses only.
With the feature White List IP Address, NAVAN makes it possible to entertain requests on its Ethernet WAN port for
predefined IP Addresses only.
How it works
For this feature to work,
• make sure the Enable IP Address based call traffic restriction flag is 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 “ Enable 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
NAVAN.
• Call Restriction will be applied 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
10 IP Addresses. For each IP Address enter the corresponding Subnet Mask.
• With the White List Tables ready, follow these steps:
• Log into Jeeves as the System Engineer.
• Click the PBX Settings tab.
