It preserves source ip, so that suggests something like a kernel module, or like Intel's DPDK. Either (practically) rules out anything but C, doesn't it?

Or they could just encapsulate the packet to preserve the IP...

Happy to be educated. There's some easy way to alter the destination IP that way?

Like mention above IPVS: http://www.linuxvirtualserver.org/VS-IPTunneling.html

This is heavily used by Facebook for their loadblancer on their racks.

Ah, ok. A kernel module, as I mentioned :)
