udpfwd

udpfwd is a stateful userspace UDP port forwarder that can accomplish SNAT/DNAT. It listens for packets received on a given port, changes their source IP addresses to the address of the local host ("SNAT"), and forwards them to the destination (dest_ip:dest_port) from a randomly chosen local sending port. Once chosen, the source_ip:source_port:send_port triplet is unique, allowing for connection tracking. Conversely, when a packet is received on send_port, its destination is changed to source_ip:source_port ("DNAT"), and forwarded onwards.
