Cloudflare WAN, Magic Transit - NAT-T support for IKE on UDP port 500
UpdateUnverifiedAdded Sep 24, 2026
Cloudflare IPsec now supports the standard NAT traversal (NAT-T) flow, where IKE begins on UDP port 500 and switches to UDP port 4500 after NAT is detected. Previously, devices behind NAT had to be configured to initiate IKE on UDP port 4500 directly. Devices that started on UDP port 500 could not complete the IKE handshake when NAT was in the path.
