ini File Field Name 
Web Parameter Name 

Valid Range and Description 

EnableSTUN

 

[Enable STUN] 

0 = STUN protocol is disabled (default). 
1 = STUN protocol is enabled. 
When enabled, the gateway functions as a STUN client and 
communicates with a STUN server located in the public 
internet. STUN is used to discover whether the gateway is 
located behind a NAT and the type of that NAT. In addition, it 
is used to determine the IP addresses and port numbers that 
the NAT assigns to outgoing signaling messages (using SIP) 
and media streams (using RTP, RTCP and T.38). STUN 
works with many existing NAT types, and does not require 
any special behavior from them. 
This parameter cannot be changed on-the-fly and requires a 
gateway reset. 

STUNServerPrimaryIP

 

[STUN Server Primary IP] 

The IP address of the primary STUN server. 

STUNServerSecondaryIP

 

[STUN Server Secondary IP] 

The IP address of the secondary STUN server. 

NATBindingDefaultTimeout 

Defines the default NAT binding lifetime in seconds. STUN is 
used to refresh the binding information after this time expires.
The valid range is 0 to 2592000. The default value is 30. 

DisableNAT 

Enables / disables the Network Address Translation (NAT) 
mechanism. 
0 = Enabled. 
1 = Disabled (default). 

 

The compare operation that is performed on the IP 
address is enabled by default and is controlled by the 
parameter ‘EnableIPAddrTranslation’. The compare 
operation that is performed on the UDP port is 
disabled by default and is controlled by the 
parameter ‘EnableUDPPortTranslation’.
