In #5207, I already added logs for which assertions we are performing on ICMP packets. This PR does the same thing for the DNS queries that are being to connlib. It also adds spans that add some more context to the messages. Here is an excerpt of what this looks like: ``` Applying transition 19/19: SendICMPPacketToResource { idx: Index(3210705382108961150), seq: 57053, identifier: 28234, src: TunnelIp6 } 2024-06-05T07:06:30.742455Z INFO assertions: ✅ Performed the expected 2 ICMP handshakes 2024-06-05T07:06:30.742459Z INFO icmp{seq=15543 identifier=63125}: assertions: ✅ dst IP of request matches src IP of response: 3fb8:a7b0:c912:a648:6c9:7910:92dc:8db 2024-06-05T07:06:30.742461Z INFO icmp{seq=15543 identifier=63125}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742464Z INFO icmp{seq=15543 identifier=63125}: assertions: ✅ 3fb8:a7b0:c912:a648:6c9:7910:92dc:8db is the correct resource 2024-06-05T07:06:30.742467Z INFO icmp{seq=57053 identifier=28234}: assertions: ✅ dst IP of request matches src IP of response: 3fb8:a7b0:c912:a648:6c9:7910:92dc:8d8 2024-06-05T07:06:30.742470Z INFO icmp{seq=57053 identifier=28234}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742473Z INFO icmp{seq=57053 identifier=28234}: assertions: ✅ 3fb8:a7b0:c912:a648:6c9:7910:92dc:8d8 is the correct resource 2024-06-05T07:06:30.742477Z INFO dns{query_id=58256}: assertions: ✅ dst IP of request matches src IP of response: fd00:2021:1111:8000:100:100:111:0 2024-06-05T07:06:30.742480Z INFO dns{query_id=58256}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742483Z INFO dns{query_id=58256}: assertions: ✅ dst port of request matches src port of response: 53 2024-06-05T07:06:30.742485Z INFO dns{query_id=58256}: assertions: ✅ src port of request matches dst port of response: 9999 2024-06-05T07:06:30.742488Z INFO dns{query_id=22568}: assertions: ✅ dst IP of request matches src IP of response: 100.100.111.1 2024-06-05T07:06:30.742491Z INFO dns{query_id=22568}: assertions: ✅ src IP of request matches dst IP of response: 100.75.34.66 2024-06-05T07:06:30.742494Z INFO dns{query_id=22568}: assertions: ✅ dst port of request matches src port of response: 53 2024-06-05T07:06:30.742497Z INFO dns{query_id=22568}: assertions: ✅ src port of request matches dst port of response: 9999 2024-06-05T07:06:30.742500Z INFO dns{query_id=58735}: assertions: ✅ dst IP of request matches src IP of response: fd00:2021:1111:8000:100:100:111:2 2024-06-05T07:06:30.742502Z INFO dns{query_id=58735}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742505Z INFO dns{query_id=58735}: assertions: ✅ dst port of request matches src port of response: 53 2024-06-05T07:06:30.742507Z INFO dns{query_id=58735}: assertions: ✅ src port of request matches dst port of response: 9999 2024-06-05T07:06:30.742512Z INFO dns{query_id=59096}: assertions: ✅ dst IP of request matches src IP of response: fd00:2021:1111:8000:100:100:111:1 2024-06-05T07:06:30.742514Z INFO dns{query_id=59096}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742517Z INFO dns{query_id=59096}: assertions: ✅ dst port of request matches src port of response: 53 2024-06-05T07:06:30.742519Z INFO dns{query_id=59096}: assertions: ✅ src port of request matches dst port of response: 9999 2024-06-05T07:06:30.742522Z INFO dns{query_id=41570}: assertions: ✅ dst IP of request matches src IP of response: fd00:2021:1111:8000:100:100:111:1 2024-06-05T07:06:30.742525Z INFO dns{query_id=41570}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742527Z INFO dns{query_id=41570}: assertions: ✅ dst port of request matches src port of response: 53 2024-06-05T07:06:30.742530Z INFO dns{query_id=41570}: assertions: ✅ src port of request matches dst port of response: 9999 2024-06-05T07:06:30.742533Z INFO dns{query_id=15028}: assertions: ✅ dst IP of request matches src IP of response: fd00:2021:1111:8000:100:100:111:1 2024-06-05T07:06:30.742536Z INFO dns{query_id=15028}: assertions: ✅ src IP of request matches dst IP of response: fd00:2021:1111::a:3531 2024-06-05T07:06:30.742538Z INFO dns{query_id=15028}: assertions: ✅ dst port of request matches src port of response: 53 2024-06-05T07:06:30.742541Z INFO dns{query_id=15028}: assertions: ✅ src port of request matches dst port of response: 9999 ``` It is a bit repetitive because all assertions always run on all state transition. Nevertheless I've found it useful to be able to look at the assertions and visually verify that they make sense.
A modern alternative to legacy VPNs.
Note: The main branch tracks Firezone 1.x. See the
legacy branch if you're
looking for Firezone 0.7.
Read the 1.0 announcement for more.
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.
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:
- macOS / iOS: swift/apple
- Android / ChromeOS: kotlin/android
- Windows / Linux: rust/gui-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.
