Better Route network security

Never trust a forwarded-IP header merely because it exists. Configure every proxy hop that your infrastructure controls.

use BetterRoute\Middleware\Network\IpAllowlistMiddleware;
use BetterRoute\Middleware\Network\TrustedProxyClientIpResolver;

$resolver = new TrustedProxyClientIpResolver(
    trustedProxyCidrs: ['10.0.0.0/24', '2001:db8:1234::/48'],
    forwardedHeaders: ['CF-Connecting-IP', 'X-Forwarded-For']
);

$allowlist = new IpAllowlistMiddleware(
    allowedCidrs: ['203.0.113.0/24'],
    ipResolver: $resolver,
    failClosed: true
);
