Since IP forwarding, i.e. routing, is basically rewriting a packet with a different source address and shipping it out of a different network interface, I believe you could technically do static routing with the proper
There are many diagrams that are out there that illustrate exactly how a TCP/IP packet traverses the kernel (including Netfilter and the routing facility) - an example is this: http://www.adminsehow.com/2011/09/iptables-packet-traverse-map/
