IP Allow List

This page was created to help you submit a whitelist request because one of your customers, vendors, or clients is trying to connect to one of the following Thru hosted internal FTPS/SFTPS hosts:

There are two ways to submit an Allow List Request. We require this particular request to be documented.

Create a support ticket on our support page.

In the future, we may add additional methods to submit these requests.

If your customer, vendor, or client reaches out to us with a allow list request, we will ask them to contact you.

We only process allow list requests for MFT customers. Before you submit, verify the IPs are valid.

Verify Your List of IPs are Valid

Check the IP address. If you have issues determining your IPs are valid, contact your network administrator. It is important to provide MFT the correct information so your vendor, customer, or client can connect successfully without any issues the first time. Public IP addresses are assigned by the Internet Corporation for Assigned Names and Numbers, and are routable over the Internet. Private IP addresses are not routable over the Internet; they are intended to be used within a facility.

tip
  • Make sure you are submitting a valid routable public IP address.
  • Only submit static public IP address.
  • Make sure the request is for an FTPS/SFTP inbound connection to Thru and not HTTPS
  • If you provide a subnet it must be below /29 which is 8 IPs. Anything higher like /28 requires evidence that documents your company owns the subnet.
