* Start IP: Specify the starting IP address in LAN and WAN (Internet)
* End IP: Specify the ending IP address in LAN and WAN (Internet)
* Overload: This is also referred to as NAPT. This type of NAT record allows
ou to use a single Internet IP address to connect multiple LAN machines to
Internet.. When this NAT record is associated with a policy, matching
packets will be subject to NAT using this Internet IP address. It also
manages port translation.
* NAT IP Address: Specify a single NAT IP Address
* Interface: This is similar to NAPT (Internet IP). The only difference is that
this setting takes the external interface as the Internet IP address. The IP
address of the interface connected to the Internet will be used as the NAT
IP address.
Note: If the static type NAT record is used in an Internet policy then
packets from LAN to Internet with attributes that match this policy will
be subject to NAT such that the source IP address of the packet gets
modified to the corresponding IP address which is a public address.
The source IP address of the packet should fall into the set of LAN IP
Addresses. If the static type NAT record is used in an Internal Service
policy then packets from Internet to LAN with attributes that match this
policy will be subject to NAT such that the destination IP address of
the packet gets modified to the corresponding IP address which is a
private network address. The destination IP address of the packet
should fall into the set of LAN IP addresses.
