Weather Update - Grandstream Networks GXP1450 User Manual

If the devices are kept within a private network behind a firewall, we recommend using STUN Server. The
following settings are useful in the STUN Server scenario:

STUN Server
Under Settings->General Settings, enter a STUN Server IP (or FQDN) that you may have, or look up
a free public STUN Server on the
internet and enter it on this field. If using Public IP, keep this field blank.

Use Random Ports
It is under Settings->General Settings. This setting depends on your network settings. When set to
"Yes", it will force random generation of
both the local SIP and RTP ports. This is usually necessary when multiple GXPs are behind the
same NAT. If using a Public IP address, set this parameter to "No".

NAT Traversal
It is under Accounts X->Network Settings. Default setting is "No". Enable the device to use NAT
traversal when it is behind firewall on a private
network. Select Keep-Alive, Auto, STUN (with STUN server path configured too) or other option
according to the network setting.
