3-2-4 Advanced Network 
3-2-4-1 ALG 
ALG (Application Layer Gateway) is also named the third generation firewall. When the user on the trusted 
network wants to connect to the untrusted network (Internet), the application will be guided to the proxy 
server of the firewall. The proxy server disguises the actual server on the Internet. It can estimate the 
request, and decides the permission or deny of the request according to the rule in a suit of unit network 
service.
