Virtual Private
Network (VPN)
VPN provides the secure communication method for the remote
computers via the WAN. If the hosts in the internal network need
to use the VPN protocols such as PPTP, L2TP, and IPSec to
connect to the remote VPN network, you should enable the
corresponding passthrough function.
Application
Layer Gateway
(ALG)
ALG provides network address and port conversion for some
application layer protocols such as FTP, and SIP that adopt
“control/data” mode when passing through the NAT gateway. It is
recommended you enable the ALG functions.

6.7.2 Advanced Security Settings
The goal of DoS (Denial of service) attack is using a large quantity of illusive
information to exhaust the resources of the destination host. The destination host is
forced to process the illusive traffic, which affects the processing of the legal traffic. If
the DoS attack is from the multiple source addresses, it is also called DDoS
(Distribution Denial of service) attack. Generally, all the source addresses of the DoS
attack and DDoS attack are fraudulent.
