Create snat failed using rest api

I believe this seems to do what you are asking.

curl -sku admin:admin https://192.168.10.23/mgmt/tm/ltm/snat -H "content-type:application/json"  -d '{
      "name": "test2",
      "partition": "Common",
      "autoLasthop": "enabled",
      "mirror": "disabled",
      "sourcePort": "preserve",
      "translation": "/Common/192.168.1.3",
      "vlansEnabled": true,
      "vlans": [
        "/Common/EXTERNAL"
      ],
      "origins": [
        {
          "name": "::/0"
        },
        {
          "name": "0.0.0.0/0"
        }
      ]
    }'
