I test netbird all work perfectly but the masquerade don't work on debian 11

I capture packet on node with route configured and in pcap it's show the IP addresses of host behind the other node netbird

explanation:

PC --------> NETBIRD A ---------> NETBIRD B ----------> DNS

I see the source IP of the PC when I should see the IP of NETBIRD B
