13.Use Private IP (Behind NAT)
Using a Private IP in a NAT Environment
The IPS unit is able to communicate with other IPS units under a NAT environment using Private IP addresses on the LAN side of your IP Sharing device. However you must configure the IP Sharing device to treat the IPS unit as a Virtual Server using UDP port 5060, 2000.
You will have to ask MIS personnel to enable the ports listed in the following table.
Packet Modes | Using Ports | |
SIP Signal Packets | UDP 5060 | |
|
|
|
IPS | Signaling Port | UDP 2000 |
|

IPS | RTP Base Port | UDP 4000 |

If you want to use private IP behind NAT and Proxy Server is in Internet, you must need to enable STUN service. If the system is installed in VPN, it is not necessary to Enable Stun.
