Thomas Eizinger 81da120c17 fix(phoenix-channel): report connection hiccups to upper layer (#8203)
The WebSocket connection to the portal from within the Clients, Gateways
and Relays may be temporarily interrupted by IO errors. In such cases we
simply reconnect to it. This isn't as much of a problem for Clients and
Gateways. For Relays however, a disconnect can be disruptive for
customers because the portal will send `relays_presence` events to all
Clients and Gateways. Any relayed connection will therefore be
interrupted. See #8177.

Relays run on our own infrastructure and we want to be notified if their
connection flaps.

In order to differentiate between these scenarios, we remove the logging
from within `phoenix-channel` and report these connection hiccups one
layer up. This allows Clients and Gateways to log them on DEBUG whereas
the Relay can log them on WARN.

gateway

This crate houses the Firezone gateway.

Building

You can build the gateway using: cargo build --release --bin firezone-gateway

You should then find a binary in target/release/firezone-gateway.

Running

The Firezone Gateway supports Linux only. To run the Gateway binary on your Linux host:

  1. Generate a new Gateway token from the "Gateways" section of the admin portal and save it in your secrets manager.
  2. Ensure the FIREZONE_TOKEN=<gateway_token> environment variable is set securely in your Gateway's shell environment. The Gateway requires this variable at startup.
  3. Set FIREZONE_ID to a unique string to identify this gateway in the portal, e.g. export FIREZONE_ID=$(uuidgen). The Gateway requires this variable at startup.
  4. Now, you can start the Gateway with:
firezone-gateway

If you're running as a non-root user, you'll need the CAP_NET_ADMIN capability to open /dev/net/tun. You can add this to the gateway binary with:

sudo setcap 'cap_net_admin+eip' /path/to/firezone-gateway

Ports

The gateway requires no open ports. Connections automatically traverse NAT with STUN/TURN via the relay.
