工具介绍

一款基于 epoll/libev 的轻量级端口映射/转发工具,支持 IPv4 和 IPv6 (适用于 TCP 和 UDP)

tinyPortMapper (or tinyPortForwarder)

A Lightweight High-Performance Port Mapping/Forwarding Utility using epoll, Supports both TCP and UDP

Supported Platforms

Linux host (including desktop Linux,Android phone/tablet, OpenWRT router, or Raspberry PI). Binaries of amd64 x86 mips_be mips_le arm are provided.

Getting Started

Installing

Download binary release from https://github.com/wangyu-/tinyPortMapper/releases

Running

Assume you want to map/forward local port 1234 to 10.222.2.1:443

# for both TCP and UDP
./tinymapper_amd64 -l0.0.0.0:1234 -r10.222.2.1:443 -t -u

# for TCP only
./tinymapper_amd64 -l0.0.0.0:1234 -r10.222.2.1:443 -t

# for UDP only
./tinymapper_amd64 -l0.0.0.0:1234 -r10.222.2.1:443 -u

# for ipv6, both TCP and UDP
# ipv6 address must be surrounded with `[]`, ipv4 address must NOT be surrounded with `[]`
./tinymapper_amd64 -l[::]:1234 -r[2001:19f0:7001:1111:00:ff:11:22]:443 -t -u

NOTE

# local port and remote port can be the same
./tinymapper_amd64 -l0.0.0.0:443 -r10.222.2.1:443 -u

# you can also use 6-to-4 or 4-to-6 forward
./tinymapper_amd64 -l0.0.0.0:1234 -r[2001:19f0:7001:1111:00:ff:11:22]:443 -t -u
./tinymapper_amd64 -l[::]:1234 -r44.55.66.77:443 -t -u

# you can also use ipv4-mapped ipv6 address
# this is especially useful if you want to play with ipv6 and you dont have a real ipv6 address
./tinymapper_amd64 -l[::]:4433 -r[::ffff:10.222.2.1]:443 -t -u
./tinymapper_amd64 -l[::ffff:0.0.0.0]:4433 -r[::ffff:10.222.2.1]:443 -t -u
