## Connectivity Requirements

Tunnel uses [Cloudflare Tunnels](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps) and requires connectivity to Cloudflare to function properly.

No inbound connectivity to the container is required by Tines from the internet or elsewhere. The container will attempt to form a connection with the services below from its deployment location.

| DESTINATION | PORT | PROTOCOLS | DIRECTION | Purpose |
| --- | --- | --- | --- | --- |
| [region1.v2.argotunnel.com](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/deploy-tunnels/tunnel-with-firewall/#required-for-tunnel-operation) | 443,7844 | TCP/HTTPS | Outbound | Establishes a secure tunnel for outbound connections to Cloudflare's network. |
| [region2.v2.argotunnel.com](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/deploy-tunnels/tunnel-with-firewall/#required-for-tunnel-operation) | 443,7844 | TCP/HTTPS | Outbound | Establishes a secure tunnel for outbound connections to Cloudflare's network. |
| [api.cloudflare.com](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/deploy-tunnels/tunnel-with-firewall/#optional) | 443,7844 | TCP/HTTPS | Outbound | Accesses Cloudflare's API for management tasks (not required for core functionality). |
| [update.argotunnel.com](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/deploy-tunnels/tunnel-with-firewall/#optional) | 443,7844 | TCP/HTTPS | Outbound | Checks and downloads updates for the Argo Tunnel service. |
| [<your-tunnel-name>-<your-tenant-name>.tines-tunnel.com](tines-tunnel.com) | 443,7844 | TCP/HTTPS | Outbound | Facilitates secure, outbound-only connections to Tines services. |
| [registry.hub.docker.com](https://registry.hub.docker.com/r/tines/tines-tunnel) | 443,7844 | TCP/HTTPS | Outbound | Required to pull the Tines Tunnel image from Docker Hub. |

> **IMPORTANT:** The requirements listed here apply to your firewall configuration so ensure these outbound connections are allowed.
