The Interface Details screen appears, displaying the statistics you selected. The
screen defaults to showing real-time data, for which it polls the router every
10 seconds. If the interface is up and there is data transmitting across it, you
should see an increase in the number of packets and bytes transferred across the
interface.
How Do I Configure NAT on a WAN Interface?

Step2 Click NAT in the left frame.
Step3 In the NAT window, click Designate NAT interfaces.
Step4 Find the interface for which you want to configure NAT.
Step5 Check inside(trusted) next to the interface to designate the interface as an inside,
or trusted interface. An inside designation is typically used to designate an
interface serving a LAN whose resources. must be protected. Check
outside(untrusted) to designate it as an outside interface. Outside interfaces
typically connect to an untrusted network. Click OK.
The interface is added to the pool of interfaces using NAT.

to add, delete, or modify a rule, click the appropriate button on the NAT window
to perform the configuration you need.
