PAT map multiple private hosts to one publicly exposed IP address

Port Address Tranlation is also called porting, port overloading,

port-level multiplexed NAT and single address NAT.

NAT provides a one-to-one translation of IP addresses. RFC 2663 refers to

this type of NAT as basic NAT; it is often also called a one-to-one NAT

Static NAT is a type of NAT in which a private IP address is mapped to a

public IP address, where the public address is always the same IP

address. This allows an internal host, such as a Web server, to have an

unregistered (private) IP address and still be reachable over the Internet.

Enable Load Balancing in Weighted LB mode

In Weighted Load Balancing (LB) mode, the balance weights are calculated

based on WAN link speed and available WAN bandwidth. This is the default and

most efficient balancing algorithm.
