corresponding
Policy Route rule
for NAT 1:1
mapping.
If the server will initiate sessions to the clients, select this check box to create a
corresponding policy route so the ZyWALL uses the same public IP address as the
traffic’s source address. This is called NAT 1:1.
Or you can click Policy Route to go to the screens where you can manually
configure a NAT 1:1 policy route for this virtual server.
See NAT 1:1 Example on page 313 for an example of NAT 1:1.
