  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.
