Modal Networking

Use this skill when configuring network behavior for Modal Functions, including static IPs, port forwarding, region selection, and inter-container communication.

For Server routing_region / compute_region on @app.server, see modal-servers. Auto Endpoints expose the same placement flags via CLI (modal-endpoints).

When to Use This Skill

• Need a static outbound IP for allow-listing
• Exposing internal container ports to the internet
• Running Functions near specific cloud regions
• Optimizing network latency with regional routing
• Connecting Functions to external private networks

Proxies (Static IP)

Route all container traffic through static IP addresses:
