Setting up DMZ host

Allowing SIP request through NAT
NAT checks IP header only and translate the information into private IP address.
However, for applications that demand many dynamic ports for session control such as
Session Initiation Protocol (SIP), traditional NAT cannot translate the address because
lack of preset service ports. To enable such services while at the same time do not
sacrifice network security, DSL-N13 introduces Application Layer Gateway (ALG) to
allow SIP request going through fireware and NAT from WAN. To configure ALG:
1. Click
Advanced Setup -> NAT -> ALG

configuration page.
