Original Pull Request: https://github.com/netbirdio/netbird/pull/915

State: closed
Merged: Yes

Describe your changes

With old management, the new clients always will receive an empty list of firewall rules, and by default, we block all traffic. To avoid this, let’s modify the protocol and add FirewallRulesIsEmpty field (same as RemotePeersIsEmpty). When this field is not set and rules are empty, we work with the old management version, and we need to add special rules to input and output chains to allow all traffic.

Checklist

Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
