## Architecture
- OpenVPN server listens locally on TCP `1194`
- Cloudflare Tunnel ingress routes `vpn.bhatfamily.in` to `tcp://localhost:1194`
- Cloudflare Tunnel ingress routes `vpn.bhatfamily.in` to `tcp://127.0.0.1:1194`
- Clients connect through local `cloudflared access tcp` forwarding, then OpenVPN to localhost

## Cloudflared Ingress Baseline
Expected entries in `/etc/cloudflared/config.yml`:
- `vpn.bhatfamily.in -> tcp://localhost:1194`
- `vpn.bhatfamily.in -> tcp://127.0.0.1:1194`
- Existing routes:
- `web.bhatfamily.in -> http://localhost:8080`
- `ecom.bhatfamily.in -> http://localhost:8081`
- `ssh.bhatfamily.in -> ssh://localhost:22`
## DNS Route Baseline
Expected DNS route for this tunnel:
- `vpn.bhatfamily.in CNAME 6a2e99c2-ce2c-49a9-a3f2-8bf1ad3073b0.cfargotunnel.com`

- `cloudflared access tcp --url localhost:1194` may fail with `address already in use` if local OpenVPN server is already bound to `1194` on that machine.
- Use another local forwarder port (e.g. `21194`) and set OpenVPN client `remote 127.0.0.1 21194`.
- `vpn.bhatfamily.in:21194` is not meant to be publicly reachable; it is client-local forwarding endpoint semantics.
- If DNS resolves to `bhatfamily.in` (or any non-`cfargotunnel.com` CNAME), Cloudflare will not route traffic to this tunnel; repair the DNS route with `cloudflared tunnel route dns`.
