10.5 The DMZ Screen
In addition to the servers for specified services, NAT supports a default server IP address. A default
server receives packets from ports that are not specified in the
NAT Port Forwarding Setup
screen.
Figure 81
Network Setting > NAT > DMZ
The following table describes the fields in this screen.
10.6 The ALG Screen
Some NAT routers may include a SIP Application Layer Gateway (ALG). A 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 your Device is behind a SIP ALG.
Use this screen to enable and disable the NAT and SIP (VoIP) ALG in the Device. To access this
screen, click
Network Setting > NAT > ALG
.
