PRIVATE_NETWORK . fetch ( "http://10.50.0.100:8080/api" ) ; Note For destinations behind Cloudflare WAN on-ramps (GRE, IPsec, or CNI), your network must route the Cloudflare source IP range back through the on-ramp so reply traffic returns to Cloudflare. Without this route, stateful flows will fail. This is part of standard Cloudflare WAN onboarding. For configuration options, refer to VPC Networks . Resources API New to Cloudflare?
