Originally created by @Grokzen on GitHub (Apr 26, 2019).

Environment

Python version: 3.6.x
NetBox version: 2.5.10

Steps to Reproduce

Create an IP address that will later be used for nat_inside
Create a CSV datablob that is capable of importing a new IP address. Use another IP as the one you want to import, but set the ip address from 1. as the nat_inside address.

Expected Behavior

Import works and a new ip address is created with a nat_inside address set on it. The side-bar describes that it should be possible to import it with an nat_inside address set.

Observed Behavior

A form validation error is thrown

Row 1 nat_inside: Select a valid choice. That choice is not one of the available choices

Possible solutions.

Either remove nat_inside from the sidebar as a valid csv column.

Or add the following to the class IPAddressCSVForm

    nat_inside = FlexibleModelChoiceField(
        queryset=IPAddress.objects.all(),
        required=False,
        to_field_name='address',
        help_text='',
        error_messages={
            'invalid_choice': 'IP Address not found',
        }
    )

and you would be able to import nat_inside addresses again.

Where do you see this? nat_inside is not a supported field for IP address imports in v2.5.10, and I'm fairly sure it hasn't ever been. Are you running a custom fork?

Where do you see this? `nat_inside` is not [a supported field](https://github.com/digitalocean/netbox/blob/master/netbox/ipam/models.py#L589) for IP address imports in v2.5.10, and I'm fairly sure it hasn't ever been.

You are correct, it had snuck in to the csv_headers as a part of extending the export part and it looked like it was supported by default for import part as well.
