Describe the bug

Hello, everyone!

I have

  1. 192.168.1.1 - Wi-Fi router
  2. 192.168.1.63 - workstation with Debian 13 and Outline Client Version 1.19.0 (490240), connected via Wi-Fi, IP assigned via DHCP.
  3. 192.168.1.240 - local file server

When I turn on Outline Client on 192.168.1.63, my local network is unavailable because Outline changes /etc/resolve.conf to

# Generated by NetworkManager
nameserver 169.254.x.x

At the same time, local IP addresses can be pinged - everything is OK, for example

ping 192.168.1.240 
ping 192.168.1.1

But, for example: mount, WinSCP, SSH connection, does not work.

mount -t nfs 192.168.1.240:/var/www /var/www

When I disable Outline, the local network becomes accessible again because Outline restores /etc/resolve.conf.

nameserver 192.168.1.1

OutLine always overwrites /etc/resolve.conf and does not allow writing similar to this:

nameserver 192.168.1.1
nameserver 169.254.x.x

Please help me figure out how to make OutLine work and the local network accessible.
