adding the routing entry is done by invoking inet_rtm_newroute() in net/ipv4/fib_frontend.c. Subsequently, insertion into the Forwarding Information
Connection Tracking allows the kernel to keep track of sessions. The Connection Tracking layer’s primary goal is to serve as the basis of NAT. The IPv4 NAT module (net/ipv4/netfilter/iptable_nat.c) cannot be built if CONFIG_NF_CONNTRACK_IPV4 is not set. Similarly, the IPv6 NAT module ...
