Forward packets Wireguard to local subnet, with Nftables.

Hi,

I would like to forward packets that come from a wireguard connection to a local subnet

environment

• Client: connected to server trough wireguard IP 192.168.X.2
• server: connected to Client trough wireguard IP 192.168.X.1 and 192.168.Y.1 ( it's not systemd free ¯(ツ)/¯  )
• aMachine: on the same subnet as server IP 192.168.Y.2

   

on the server I've done

 bash

    
#I don't know if this is necessary ?
echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf
sysctl --system

  

I've added the following rule to the nftables config on server but it seem the packet get lost ?

 nft

    
#added inside existing table `table ip Tip {}`
chain chPreRoute {
type nat hook prerouting priority 0; policy accept;
iif wg0 icmp type echo-request dnat to 192.168.Y.2
}
