User-space TCP/UDP port forwarding services
Summary
This project contains two applications: tcpfwd, udpfwd, which are for TCP and UDP port forwarding literally. Written in pure C.

tcpfwd|udpfwd <local_addr:local_port> <dest_addr:dest_port> [-d] [-o]
Options:
-d run in background
-o accept IPv6 connections only for IPv6 listener
-p <pidfile> write PID to file
Examples
Map local TCP port 1022 to 192.168.1.77:22
tcpfwd 0.0.0.0:1022 192.168.1.77:22 # allow access from all hosts
tcpfwd 127.0.0.1:1022 192.168.1.77:22 # only allow localhost
tcpfwd [::]:1022 192.168.1.77:22 # allow access to port 1022 via both IPv4 and IPv6
Map local UDP port 53 to 8.8.8.8:53
udpfwd 0.0.0.0:53 8.8.8.8:53
udpfwd [::]:53 8.8.8.8:53
IPv4-IPv6 transforming
udpfwd [::]:1701 localhost:1701 # add IPv6 support for a local L2TP service
tcpfwd 0.0.0.0:80 [2001:db8:3::2]:80 # enable IPv4 access for an IPv6-only web service
