You can configure both source and destination NAT rules to disable address translation. You may
have exceptions where you don't want NAT to occur for a certain host in a subnet or
for traffic exiting a specific interface. The following procedure shows how to
disable source NAT for a host.
- Create the NAT policy.
- Select and click Add a descriptive Name for the policy.On the Original Packet tab, select the zone you created for your internal network in the Source Zone section (click Add and then select the zone) and the zone you created for the external network from the Destination Zone list.For Source Address, Add the host address. Click OK.On the Translated Packet tab, select None from the Translation Type list in the Source Address Translation section of the screen.Click OK.Commit your changes.NAT rules are processed in order from the top to the bottom, so place the NAT exemption policy before other NAT policies to ensure it is processed before an address translation occurs for the sources you want to exempt.
