1.1.1.2.
Figure 137 Creating the Public IP Address Object
7.13.3 Setup a NAT Policy for the IPPBX
Click Configuration > Network > NAT > Add.
• Configure a name for the rule (WAN-DMZ_IPPBX here).
• You want the IPPBX to receive calls from the WAN and also be able to send calls
to the WAN so you set the Classification to NAT 1:1.
•Set the Incoming Interface to ge2.
•Set the Original IP to the WAN address object (IPPBX-Public). If a domain
name is registered for IP address 1.1.1.2, users can use it to connect to for
making SIP calls.
•Set the Mapped IP to the IPPBX’s DMZ IP address object (IPPBX-DMZ).
•Set the Port Mapping Type to Port, the Protocol Type to UDP and the
original and mapped ports to 5060.
• Keep Enable NAT Loopback selected to allow the LAN users to use the IPPBX
(see NAT Loopback on page 419 for details).
