Describe the problem

W
I've created a Network with a Resource 192.168.1.0/24 and a routing peer which is a linux host running netbird in docker. When I turn off Masquerade for the routing peer the network 192.168.1.0 is no longer advertised to the connecting Windows Peer. Turning masquerade back on doesn't fix it either. I have to delete the routing peer and re-add it and the windows client will get the network again.

To Reproduce

Steps to reproduce the behavior:

Setup Network and connect windows client
On netbird management site Networks>Select Network> Edit Routing Peer > Advanced Settings Tab> Turn off Masquerade.
Refresh Networks on Windows client and Advertised network disappears.

Add any other context about the problem here.

The Routing peer list masquerade status also doesn't match what is actaully enabled if you click edit on a routing peer.
