Wireguard and martian logging

[trendy]

I didn't ask you to execute the command to a file. I didn't ask you to open it in wireshark and paste all this useless data on the thread.
If you cannot find a single host in the lan that is not so active in sending packets, you can append the and icmp at the end of the command and it will filter the ping and the reply.

^C
3 packets captured
3 packets received by filter
0 packets dropped by kernel

that's one of the servers that blocks requests

Have you added the masquerade on lan interface for packets coming from wg interface as I told you here?
It doesn't look so.
Verify it with iptables-save -c | grep -i masq

config zone
        option name 'lan'
        option input 'ACCEPT'
        option output 'ACCEPT'
        option forward 'ACCEPT'
        option network 'lan'
        option masq_src '192.168.9.0/24'

As you can see I had forgotten to activate masq now it works correctly! sorry for the mistake.
