13. Use Private IP (Behind NAT)
Using a Private IP in a NAT Environment
The gateway is able to communicate with other gateways 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 gateway 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
Gateway Signaling Port
UDP 2000
Gateway RTP Base Port
UDP 4000
FTP software upgrade

Web management
TCP 80
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.
