Original Pull Request: https://github.com/netbirdio/netbird/pull/3884

State: closed
Merged: Yes

Describe your changes

Using NB_ENABLE_LOCAL_FORWARDING=true will instruct NetBird to pass traffic for internal interfaces to the forwarder instead of to the native stack.
This can be helpful for e.g. Windows that doesn't allow access across interfaces.
