"Divert Sockets for Linux" springs to my mind..

Divert sockets enable both IP packet interception and injection on the
end-hosts as well as on routers. Interception and injection happen at
the IP layer. The intercepted packets are diverted to sockets in the
user space, thus they will not be able to reach their destination
unless they are reinjected by the user space sockets. This allows
different tricks (e.g., routing and firewall) to be played, outside
the operating system kernel, in between the packet interception and
reinjection.
