Displays the NAT type as either:

• Inside - Applies NAT on packets coming in on interfaces marked as inside. These switch 

interfaces should be private networks which are 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 which are accessible from 
anywhere on the Internet.

Displays the Direction as either:

• Source - The inside network is transmitting data over the network 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 to the records kept by the NAT engine. There the destination IP 
address is changed back to the specific internal private class IP address in order to reach 
the LAN over the switch managed network. 

Defines the packet selection criteria for NAT. NAT is applied only on packets which match a 
rule defined in the access-list. Only Standard IP and Extended IP Access List can be used.

Defines the interface through which packets get 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.
