The following table describes the fields in this screen.
10.5 The ALG Screen
Click
Network Setting > NAT > ALG
to open the
ALG
screen. Use this screen to enable and
disable the NAT Application Layer Gateway (ALG) in the Device.
The SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses
embedded in the data stream. When the Device registers with the SIP register server, the SIP ALG
translates the Device’s private IP address inside the SIP data stream to a public IP address. You do
not need to use STUN or an outbound proxy if you enable the SIP ALG.
