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