The following table describes the fields in this screen.
11.5 ALG
Application Layer Gateway (ALG) allows customized NAT traversal filters to support address and port
translation for certain applications such as File Transfer Protocol (FTP), Session Initiation Protocol (SIP), or
file transfer in Instant Messaging (IM) applications. It allows SIP calls to pass through the Zyxel Device.
When the Zyxel Device registers with the SIP register server, the SIP ALG translates the Zyxel 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 Zyxel Device is behind a SIP ALG.
