I wanted a subdomain to give me access to my JetKVM, but running a full tunnel into the KVM's web UI had auth complications and felt fragile.
JetKVM has a native cloud feature at app.jetkvm.com. Instead of proxying traffic, I set up a Cloudflare redirect rule that sends anyone hitting the my subdomain directly to my device's cloud URL.
subdomain@yourdomain.com
- Redirect URL: https://app.jetkvm.com/devices/your-device-id
- Type: 302 (temporary, easy to change later)
kvm — just a dummy A record pointing to 192.0.2.1 (documentation IP) with proxy enabled. The redirect fires before the request ever resolves.
Visiting by subdomain now bounces straight to the JetKVM cloud console. Clean URL, no tunnel overhead, no exposed ports.
Tip: Use 301 once you're sure it's permanent. Browsers cache 301s aggressively, so stick with 302 during testing.
