Describe the problem

Some machine with installed Netbird is unavailable from remote network.

To Reproduce

I have "home" network, ex. 192.168.x.0/24, network from 5 machine 192.168.x.1 - 5. Machine 192.168.x.1 have DSM + Netbird 0.60.7, 192.168.x.3 have TrueNAS + Netbird 0.60.7, other without Netbird.
And I have "remote" notebook with Netbird 0.60.7.
Connect with "remote" to "home" configured. Address 192.168.x.2 and 192.168.x.4-5 ping successful. But if address 192.168.x.1 ping success then 192.168.x.3 fail and round. Success connect to client with installed Netbird is random.
Early from version 0.60.4-0.60.5 work without problem.

Is any other VPN software installed?

Other vpn down for work Netbird.

Append info.
Not access to route client destination network. If active route over 192.168.x.1 then access to all exclude 192.168.x.1 address.

Append info.
Policy only remote peer to home lan - to peer via her access is unavailable. Append policy remote peer to home peers group - full access. This is an excessive solution.
