Jack Carter 84a3532943 docs: add Masquerade configuration page (#751)
* docs: add Masquerade configuration page

Documents persistent return-route setup on the destination host when
masquerade is disabled on a routing peer. Covers Netplan, systemd-networkd,
NetworkManager, ifupdown, and RHEL legacy network-scripts, plus verification
and a security note. Resolves the previously dangling "Related" tile in
how-routing-peers-work.mdx.

* docs: clarify masquerade page and trim persistent recipes

- Netplan: show as a fragment with addresses/default route context so readers
  don't paste it as a standalone file
- systemd-networkd: note the drop-in needs a matching .network file and
  point at networkctl status to find it
- Test section: add ping/curl reachability examples
- Verify section: call out that proto/onlink/metric fields are normal
- Remove NetworkManager, ifupdown, and RHEL legacy sections

* docs: clarify netplan section when /etc/netplan is empty

Lead with the common case (cloud-init / installer yaml already exists),
and call out the placeholders in the example. Add a fallback path for
the rare case where /etc/netplan/ is empty.

* docs: comment <IFACE> placeholder in netplan example

* docs: clarify <IFACE> is the destination's LAN interface

* docs: comment <PEER_LAN_IP> placeholder in netplan example

* docs: tighten <PEER_LAN_IP> comment to 'local IP on this subnet'

* docs: make 'pick one' explicit for the persistent-config methods

Replace the weak one-liner with a bold "pick one" callout and a
two-bullet decision criterion (ls /etc/netplan/) so readers don't
mistake the two H3 sections for sequential steps.

* docs: add 'Find your account's NetBird range' to the masquerade page

Mirror the section already on the site-to-vpn page so readers learn to
use their account's /16 block rather than pinning the whole /10. Same
prose and netbird status recipe; trailing line adapted to reference
100.64.0.0/10 (the placeholder used elsewhere on this page).

* docs: remove 'Related' Tiles block from masquerade page

* docs: align security warning with the recommended /16 range

* docs: restore cross-link from advanced-configuration to masquerade

* docs: drop ping from the test-route example

ping would fail for ACL reasons (not routing reasons) on policies
scoped to specific TCP ports, misdirecting troubleshooting. Use curl or
nc against an allowed port instead.

* docs: apply review findings to masquerade page and legacy warning

masquerade.mdx
- add "Disable masquerade on the routing peer" section (dashboard +
  API path), so the page actually documents the toggle, not just
  the prerequisite
- "What changes when masquerade is off": say the route lives on the
  destination host (or its gateway for multi-hop)
- forward-ref "Find your account's NetBird range" from the inputs
  list to remove the substitute-then-rewind loop
- ip route del: include via <PEER_LAN_IP> so the test takedown is
  unambiguous
- netplan prose: spell out that you append to the existing routes:
  list, not add a second routes: key (YAML rejects that)
- verify output: use 192.168.1.10 for the routing peer so it stops
  colliding with the 192.168.1.50 used as the destination's own IP
  in the netplan example
- add an end-to-end verification step (curl + tcpdump) so a reader
  confirms source IPs are actually preserved, not just that a route
  exists in the table

advanced-configuration.mdx
- rewrite the contradictory Warning so it scopes correctly to legacy
  Network Routes (which match peer NetBird IPs only) and points
  readers to the Networks path when they want policy-layer ACLs
  with masquerade off

* docs: promote the /16 substitution reminder to a Note callout

* docs: clearer wording for the /16 substitution Note

The NetBird documentation

This repository contains assets required to build the documentation website for NetBird. It is built using Next.js with MDX support, a modern React framework for building static and dynamic websites.

We're glad that you want to contribute!

Requirements

  • node 16
  • npm 8+

Installation

$ npm install

Local Development

$ npm run dev

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Contributing to the docs

You can click the Fork button in the upper-right area of the screen to create a copy of this repository in your GitHub account. This copy is called a fork. Make any changes you want in your fork, and when you are ready to send those changes to us, go to your fork and create a new pull request to let us know about it.

Once your pull request is created, a NetBird reviewer will take responsibility for providing clear, actionable feedback. As the owner of the pull request, it is your responsibility to modify your pull request to address the feedback that has been provided to you by the NetBird reviewer.

Also, note that you may end up having more than one NetBird reviewer provide you feedback or you may end up getting feedback from a NetBird reviewer that is different than the one initially assigned to provide you feedback.

Furthermore, in some cases, one of your reviewers might ask for a technical review from a NetBird author when needed. Reviewers will do their best to provide feedback in a timely fashion but response time can vary based on circumstances.
