NAT
Table 9-4 General Settings
If your PBX is operating in a network connected to the internet through a single router, your PBX is
behind NAT. The NAT device has to be instructed to forward the right inbound packets (from internet)
to the PBX server. Usually you have to configure NAT settings when you want to register a remote
extension to the PBX or when you need connect to the PBX via SIP trunk.
XonTel XT-60/XT-120 supports 3 methods to configure NAT: STUN, External IP Address and External
Host. You can select one method to configure NAT or disable NAT.
1) STUN
Figure 9-2 STUN
Option
Description
STUN Address
Choose a STUN address in the drop-down list or
customize with a STUN address and STUN port.
External Refresh Interval
If an external host has been supplied, you may specify
how often the system will perform a DNS query on this
host. This value is specified in seconds.
Local Network Identification
Used to identify the local network using a network
number/subnet mask pair when the system is behind a
NAT or firewall. Some examples are as follows:
“192.168.0.0/255.255.0.0”, “10.0.0.0/255.0.0.0”, and
“172.16.0.0/12”.
