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.

OPTIONS

       -s <server_ip>
           IP address of shadowsocks remote server

       -l <local_port>
           Port number of shadowsocks local server

       -S <server_ip>
           IP address of shadowsocks remote UDP server

       -L <local_port>
           Port number of shadowsocks local UDP server

       -i <ip_list_file>
           a file whose content is bypassed ip list

       -a <lan_ips>
           LAN IP of access control, need a prefix to define access control mode

       -b <wan_ips>
           WAN IP of will be bypassed

       -w <wan_ips>
           WAN IP of will be forwarded

       -e <extra_options>
           Extra options for iptables

       -o
           Apply the rules to the OUTPUT chain

       -u
           Enable udprelay mode, TPROXY is required

       -U
           Enable udprelay mode, using different IP and ports for TCP and UDP

       -f
           Flush the rules

       -h
           Show this help message and exit

EXAMPLE

       ss-nat requires iptables(8). Here is an example:

           # Enable NAT rules for shadowsocks,
           # with both TCP and UDP redirection enabled,
           # and applied for both PREROUTING and OUTPUT chains
           root@Wrt:~# ss-nat -s 192.168.1.100 -l 1080 -u -o

           # Disable and flush all NAT rules for shadowsocks
           root@Wrt:~# ss-nat -f
