I would recommend you to rent a virtual private server (VPS) with static IP and use it as a jump machine to access your client's FTP server from a constant address.

Now there are many particular terminologies each vendor might use, but if it's OK to use Amazon Web Services, then you might be looking for an EC2 nano instance configured with an Elastic IP.

  @MohammedGadiwala If you FTP client supports SOCKS then run ssh -N -D 127.0.0.1:50000 <username for GCP>@<GCP instance hostname> on your computer, set your FTP client to use passive mode and use 127.0.0.1:50000 as SOCKS proxy, and you're good to go.
