Type Displays the NAT type as either:
•
Inside - Applies NAT on packets arriving on interfaces marked as inside. These interfaces should be private
networks not accessible from outside (public) networks.
•
Outside - Applies NAT on packets coming in on interfaces marked as outside. These switch interfaces should be
public or outside networks accessible from anywhere on the Internet.
Direction Displays the direction as either:
•
Source - The inside network is transmitting data over the network to its intended destination. On the way out,
the source IP address is changed in the header and replaced by the (public) IP address.
•
Destination - Packets passing through the NAT on the way back to the switch managed LAN are searched
against the records kept by the NAT engine. The destination IP address is changed back to the specific internal
private class IP address to reach the LAN over the switch managed network.
Access List Defines the packet selection criteria for NAT. NAT is applied only on packets which match a rule defined in the
access-list. Only the Standard IP and Extended IP Access List can be used.
Interface Defines the interface through which packets are routed. The source IP address and source port number (only if IP
protocol is TCP or UDP) of packets is changed to the interface IP address and a random port number.
NAT Address This is the IP address used during NAT. The users can configure this address.
