Original: AI Agent Cannot Reach Peer on Another Cloud? Here's the Fix

Short summary

Explains why AI agents on different clouds cannot reach each other by default — security groups block inbound, NAT hides peers, and ingress controllers are built for human traffic. Covers three common fixes (public IP, VPN mesh, message broker) with tradeoffs, then introduces Pilot Protocol, an open-source overlay network giving each agent a permanent virtual address with encrypted UDP tunnels and NAT traversal.

  • •Cross-cloud agent connectivity fails due to firewalls, NAT, and ingress assumptions
  • •Three conventional fixes compared with tradeoffs
  • •Pilot Protocol offers overlay-based virtual addressing for agents

Generated with AI, which can make mistakes.
