- Go to Policy & Objects > IPv4 Policy and create a new policy.
- Set Incoming Interface to your internal network’s interface and set Outgoing Interface to the SD-WAN interface.
- Enable NAT and apply Security Profiles as required.
- Enable Log Allowed Traffic for All Sessions to allow you to verify the results later.
