Thomas Eizinger a1049b7d78 feat(connlib): suspend if we don't have UDP sockets (#6398)
Previously, failing to bind to any interfaces was a hard-error. In
reality and in `connlib`'s current state, this is quite unlikely because
machines will at least have a loopback interface that we will bind to.

However, with #6382 in the pipeline, it may be more likely that we
actually end up with no functional UDP sockets. Furthermore, we are
considering to extend those connectivity checks in the future.

Thus, it is important that the case of "no available UDP sockets" is
gracefully handled.

Instead of failing with a hard-error, we now suspend `connlib's` network
stack. The connectivity to the portal is unaffected by this and we will
still also receive commands from the client application like `reset`.
When we receive a `reset`, we attempt to rebind the sockets and thus
retry connectivity.

Because we are suspending the entire eventloop, this won't send any
messages or trigger any timers whatsoever. For example, if we
hypothetically started up without network interfaces, this is now the
log output:

Overview

Firezone is an open source platform to securely manage remote access for any-sized organization. Unlike most VPNs, Firezone takes a granular, least-privileged approach to access management with group-based policies that control access to individual applications, entire subnets, and everything in between.

architecture

Features

Firezone is:

  • Fast: Built on WireGuard® to be 3-4 times faster than OpenVPN.
  • Scalable: Deploy two or more gateways for automatic load balancing and failover.
  • Private: Peer-to-peer, end-to-end encrypted tunnels prevent packets from routing through our infrastructure.
  • Secure: Zero attack surface thanks to Firezone's holepunching tech which establishes tunnels on-the-fly at the time of access.
  • Open: Our entire product is open-source, allowing anyone to audit the codebase.
  • Flexible: Authenticate users via email, Google Workspace, Okta, Entra ID, or OIDC and sync users and groups automatically.
  • Simple: Deploy gateways and configure access in minutes with a snappy admin UI.

Firezone is not:

  • A tool for creating bi-directional mesh networks
  • A full-featured router or firewall
  • An IPSec or OpenVPN server

Frequently asked questions (FAQ)

Can I self-host Firezone?

Our license won't stop you from self-hosting the entire Firezone product top to bottom, but our internal APIs are changing rapidly so we can't meaningfully support self-hosting Firezone in production at this time.

If you're feeling especially adventurous and want to self-host Firezone for educational or hobby purposes, follow the instructions to spin up a local development environment in CONTRIBUTING.md.

The latest published clients (on App Stores and on releases) are only guaranteed to work with the managed version of Firezone and may not work with a self-hosted portal built from this repository. This is because Apple and Google can sometimes delay updates to their app stores, and so the latest published version may not be compatible with the tip of main from this repository.

Therefore, if you're experimenting with self-hosting Firezone, you will probably want to use clients you build and distribute yourself as well.

See the READMEs in the following directories for more information on building each client:

How long will 0.7 be supported until?

Firezone 0.7 is currently end-of-life and has stopped receiving updates as of January 31st, 2024. It will continue to be available indefinitely from the legacy branch of this repo under the Apache 2.0 license.

How much does it cost?

We offer flexible per-seat monthly and annual plans for the cloud-managed version of Firezone, with optional invoicing for larger organizations. See our pricing page for more details.

Those experimenting with self-hosting can use Firezone for free without feature or seat limitations, but we can't provide support for self-hosted installations at this time.
