4.5.3 VPN Parameter
A virtual private network (VPN) is a network that uses primarily public telecommunication infrastructure,
such as the Internet, to provide remote offices or traveling users access to a central organizational
network.
VPNs typically require remote users of the network to be authenticated, and often secure data with
encryption technologies to prevent disclosure of private information to unauthorized parties.

4.5.4 ARP
The ARP function mainly used to query and add the map of IP and MAC. There are static or dynamic
ARP entries.
Like other routers, the gateway can automatically find the network device on the same segment. But,
sometimes you don't want to use this automatic mapping; you'd rather have fixed (static) associations
between an IP address and a MAC address. Gateway provides you the ability to add static ARP entries
to:
Protect your network against ARP spoofing
Prevent network confusion as a result of misconfigured network device
