Static IP address whitelisting for payment gateway

[ignoramous]

Hi Moses. Fly doesn’t yet support this. Though, one day they might:

Anycast IP as TCP source IP

They’re not! But if that’s what you’re after, we are working on a way to give instances known, permanent IPs. Assuming you want the same egress IPv4 after each deploy, we should have a way to do that soon.

If you so choose, there exist workarounds like proxying traffic through another provider that assign you a static IP for a fee (admittedly, an expense you can do without).

Outbound IP Address

We still don’t have the plumbing to give people stable outbound IPs. For now, the simplest thing is either quotaguard.com or VMs from someone like DigitalOcean running a proxy (Smokescreen would be pretty easy: GitHub - fly-apps/smokescreen: An example of deploying Smokescreen on Fly.io)
