Original GitHub issue: https://github.com/netbirdio/netbird/issues/2219

First, I really like seeing this project getting more stable every day :)

Describe the problem

Setup: A Bind DNS Server for resolving internal dns A records. With enabled MacOS Firewall, I can not resolve this internal dns records.

Maybe related to #608

I can not resolve

To Reproduce

Having a custom dns configured in netbird
Enabling the macos firewall
Netbird should ask for permission
problems resolving the custom dns entries

Expected behavior

Records should be resolved.

Are you using NetBird Cloud?

Self Hosted Netbird
netbird:
# https://hub.docker.com/r/netbirdio/management/tags
server: 0.27.7
coturn: 4
# https://hub.docker.com/r/netbirdio/dashboard
dashboard_ng: v2.3.0

NetBird version

0.28.3

NetBird status -d output:

Because its working after I disable the firewall, I don't think its an issue of netbird itself.

Screenshots

Additional context

After denying netbird incoming connections by the firewall dialog, the dns resolving seems working, but no connection can be established (I can see issues with STUN server, which seems legit to me as incoming connections will be blocked)
Temporary solution for me is disabling the macOS firewall.
