===============================================

Part 1

Get ready:

1.Raspberry Pi 21 x

2.USB can not network card one (I use this: tp-linktl-wn725n)

First, install the raspberry. (System installation is no longer described)

Second, the installation of the driver, the main reference: https://www.raspberrypi.org/forums/viewtopic.php?p=462982#p462982

Download the corresponding driver installation.

Third, installation isc-dhcp-server and configuration

Edit "/etc/network/interfaces" and add the static IP address information for wlan0 . You can learn about the static IP addresses in our SSH and static IP address tutorial.

sudo vim/etc/network/interfaces

Place a "#" sign in front of the lines which mention wlan0 wpa and, except for " allow hotplug wlan0 ". Then add the following lines to the file:

Iface wlan0 inet staticaddress 192.168.42.1netmask 255.255.255.0
Gateway 192.168.1.1

The bottom half of the file would now look something like this:

Allow-hotplug Wlan0
#iface Wlan0 inet Manual
#wpa-conf/etc/wpa_supplicant/wpa_supplicant.conf
Iface wlan0 inet staticaddress 192.168.42.1netmask 255.255.255.0
Gateway 192.168.1.1

Now reboot.

Install and configure a DHCP server

Install the DHCP server:

sudo apt-get install Isc-dhcp-server

You can safely ignore any errors on not being able to start of the DHCP server at this point. Now edit the its configuration file:

sudo vim/etc/dhcp/dhcpd.conf

Add a "#" character in front of the " option domain-name " "lines like this:

#option domain-name "example.org"; #option domain-name-servers ns1.example.org, ns2.example.org;

Remove the "#" sign in front of the " authoritative; " statement like this:

# IF This DHCP server was the official DHCP server for the local# network, the authoritative directive should be uncommente d.authoritative;

At the bottom of the file add the following lines:

Subnet 192.168.42.0 netmask 255.255.255.0 {range 192.168.42.10 192.168.42.50;option broadcast-address 192.168.42.255;o ption routers 192.168.42.1;default-lease-time 600;max-lease-time 7200;option domain-name "local"; option Domain-name-servers 8.8.8.8, 8.8.4.4;}

Make the wireless adapter the default for the DHCP request:

sudo vim/etc/default/isc-dhcp-server

Change "to INTERFACES="" " INTERFACES="wlan0" "

Restart the DHCP server:

sudo service isc-dhcp-server restart

Iv. installation HOSTAPD, reference: Http://www.jenssegers.be/43/Realtek-RTL8188-based-access-point-on-Raspberry-Pi

Since We is building our own HOSTAPD version, remove the original HOSTAPD you might has installed:

sudo apt-get autoremove hostapd

On your Raspberry Pi, download and extract the source files from GitHub:

wget https://github.com/jenssegers/RTL8188-hostapd/archive/v2.0.tar.gztar -zxvf v2.0.tar.gz

Now build HOSTAPD:

cd RTL8188-hostapd-2.0/hostapdsudo make

After a while, you should is given control back to the terminal.

install

This last step would move the created HOSTAPD binary /usr/local/bin to, add a startup script and create a configuration file in .

This is to illustrate, using WPA encryption, any settings can not connect, do not know why, using WEP encryption method to connect properly

Interface=wlan0driver=nl80211#driver=rtl871xdrvssid=mypihw_mode=gchannel=6macaddr_acl=0auth_algs=1 # 1=WPA, 2=web , 3=both
# Hide ssid:0 (don ' t), 1 (use emtpy), 2 (use ASCII 0) ignore_broadcast_ssid=0#wpa=3 #1: wpa,2:wpa2,3:both#wpa_passphrase=r Aspberry #password #wpa_key_mgmt=wpa-psk#wpa_pairwise=tkip#rsn_pairwise=ccmp

Wep_default_key=0
wep_key0=1234567890

Edit This configuration file and start the HOSTAPD service:

sudo service hostapd restart[ ok ] Stopping advanced IEEE 802.11 management: hostapd.[ ok ] Starting advanced IEEE 802.11 management: hostapd.

Tell HOSTAPD where to find it configuration file by setting the default location:

sudo vim/etc/default/hostapd

Remove the "#" in front of "" and alter the line to DAEMON_CONF read:

daemon_conf= "/etc/hostapd/hostapd.conf"

Five

Configure IP routing between the Wireless and Ethernet

Edit "to /etc/sysctl.conf enable IP forwarding:

sudo vim/etc/sysctl.conf

Find the line which reads "" and uncomment the next line like this Uncomment the next line to enable packet forwarding for IPv4 :

# Uncomment the next line to enable packet forwarding for ipv4net.ipv4.ip_forward=1

Run The following command to activate forwarding now:

sudo sh-c "echo 1 >/proc/sys/net/ipv4/ip_forward"

Now turn the Pi to a router with the follow commands:

sudo iptables-t nat-a postrouting-o eth0-j masqueradesudo iptables-a forward-i eth0-o wlan0-m State--state RELATE D,established-j acceptsudo iptables-a forward-i wlan0-o eth0-j ACCEPT

and save the routing tables into the file " /etc/iptables.ipv4.nat "

sudo sh-c "Iptables-save >/etc/iptables.ipv4.nat"

Edit " /etc/network/interfaces ":

sudo vim/etc/network/interfaces

and add the following line to the end of the file. This line would restore the routing table whenever the Pi is booted:

Pre-up Iptables-restore </etc/iptables.ipv4.nat

You should now reboot your Pi and test the wireless access using a laptop, smartphone, tablet or other Wi-Fi enabled Devic E.

Create a script with VI:

vi firewall.sh

Then write the following content:

#!/usr/bin/env shiptables -t nat -N SHADOWSOCKSiptables -t nat -A SHADOWSOCKS -d a.b.c.d -j RETURN                # 这里请填写您服务器的外网IP地址iptables -t nat -A SHADOWSOCKS -d 0.0.0.0/8 -j RETURN              # 上一行、这一行和下面几行的作用iptables -t nat -A SHADOWSOCKS -d 10.0.0.0/8 -j RETURN             # 是让一些特定的网段流量不通过iptables -t nat -A SHADOWSOCKS -d 127.0.0.0/8 -j RETURN            # shadowsocks中转iptables -t nat -A SHADOWSOCKS -d 169.254.0.0/16 -j RETURN         #iptables -t nat -A SHADOWSOCKS -d 172.16.0.0/12 -j RETURN          #iptables -t nat -A SHADOWSOCKS -d 192.168.0.0/16 -j RETURN         #iptables -t nat -A SHADOWSOCKS -d 224.0.0.0/4 -j RETURN            #iptables -t nat -A SHADOWSOCKS -d 240.0.0.0/4 -j RETURN            #iptables -t nat -A SHADOWSOCKS -p tcp -j REDIRECT --to-ports 10000 # 这里填写上一步配置的"local_port"iptables -t nat -A PREROUTING -p tcp -j SHADOWSOCKS

Finally give him executable permissions and execute:

chmod a+x firewall.sh./firewall.sh
