At present, our primary indicator as to whether telemetry is active is whether we have a Sentry session. For our analytics events however, we currently require passing in the Firezone ID and API url again. This makes it difficult to send analytics events from areas of the code that don't have this information available. To still allow for that, we integrate the `analytics` module more tightly with the Sentry session. This allows us to drop two parameters from the `$identify` event and also means we now respect the `NO_TELEMETRY` setting for these events except for `new_session`. This event is sent regardless because it allows us to track, how many on-prem installations of Firezone are out there.
gateway
This crate houses the Firezone gateway.
Building
You can build the gateway using: cargo build --release --bin firezone-gateway
You should then find a binary in target/release/firezone-gateway.
Running
The Firezone Gateway supports Linux only. To run the Gateway binary on your Linux host:
- Generate a new Gateway token from the "Gateways" section of the admin portal and save it in your secrets manager.
- Ensure the
FIREZONE_TOKEN=<gateway_token>environment variable is set securely in your Gateway's shell environment. The Gateway requires this variable at startup. - Set
FIREZONE_IDto a unique string to identify this gateway in the portal, e.g.export FIREZONE_ID=$(head -c 32 /dev/urandom | sha256sum | cut -d' ' -f1). The Gateway requires this variable at startup. We recommend this to be a 64 character hex string. - 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.
