10. Use Private IP (Behind NAT)
Using a Private IP in a NAT Environment
The unit is able to communicate with other 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 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
Signaling Port UDP 2000
RTP Base Port UDP 4000
FTP software upgrade TCP 21
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 or configure NAT WAN IP. Please refer to
9.10 STUN. If the system is installed in
VPN, it is not necessary to Enable Stun.
