On gateway I have 2 NIC. One connected to WAN through NAT and other NIC is connected to router with LAN 1(LAN Segment). On router I also have 2 NIC. One connected to gateway (LAN 1) and other NIC connected to end node (LAN2). LAN1 segment belong to 192.168.39.0/26 network and LAN2 segment belongs to 192.168.39.64/26 network. End node ip is 192.168.39.64. My question is how do we configure Masqurade on gateway for the traffic from 192.168.39.64/26 network on ubuntu 22.04? Using nftables
