If your firewall allows traffic only by domain, you may need to explicitly allow `zero-trust-client.cloudflareclient.com`.

If you are deploying the Cloudflare One Agent on Android/ChromeOS, you must also add `cloudflare-dns.com` to your firewall exception list. On Android/ChromeOS devices, WARP uses `cloudflare-dns.com` to resolve domains on your [Split Tunnel list](/cloudflare-one/connections/connect-devices/warp/configure-warp/route-traffic/split-tunnels/#domain-based-split-tunnels).
