NAME¶

ss-nat - helper script to setup NAT rules for transparent proxy

SYNOPSIS¶

ss-nat [-ouUfh] [-s <server_ip>] [-S <server_ip>] [-l <local_port>] [-L <local_port>] [-i <ip_list_file>] [-a <lan_ips>] [-b <wan_ips>] [-w <wan_ips>] [-e <extra_options>]

DESCRIPTION¶

Shadowsocks-libev is a lightweight and secure socks5 proxy. It is a port of the original shadowsocks created by clowwindy. Shadowsocks-libev is written in pure C and takes advantage of libev to achieve both high performance and low resource consumption.

ss-nat(1) sets up NAT rules for ss-redir(1) to provide traffic redirection. It requires netfilter’s NAT module and iptables(8). For more information, check out shadowsocks-libev(8) and the following EXAMPLE section.
