A Sticky IP gateway sends agent traffic from a small, fixed set of Asteroid IP addresses. Use it when a site only accepts logins from addresses it knows. There is no VPN and nothing to install. Traffic still goes over the public internet.

​
Prerequisites

Before you start, ensure that:
  • Your plan includes Sticky IP. Scale and above include it. On another plan, the option shows a plan badge; click it to upgrade, or contact the Asteroid team.

​
Set it up

  1. In Environments → Gateways, click New gateway and pick Sticky IP.
  2. Name it and click Create gateway.
  3. Ask Asteroid support for the addresses, and add them to the site’s allowlist.
  4. Pick the gateway on an environment.

​
What it can reach

Public internet only. A Sticky IP gateway refuses private ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 100.64.0.0/10), link-local and loopback addresses. To reach a private app, use Tailscale or Asteroid Tunnel.
