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 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
    [email protected]:~# ss-nat -s 192.168.1.100 -l 1080 -u -o
    
    # Disable and flush all NAT rules for shadowsocks
    [email protected]:~# ss-nat -f
