Intro::

Raspberry Pi sebagai Router Access Point.

Steps::

- sudo apt-get install hostapd udhcpd *installasi hostapd dan udhcpd
- sudo nano /etc/udhcpd.conf *update konfigurasi udhcpd

start 192.168.48.2
end 192.168.42.20
interface wlan0
remaining yes
opt dns 8.8.8.8 4.2.2.2
opt subnet 255.255.255.0
opt router 192.168.48.1 #set Rpi IP address
opt lease 864000 # 10 day DHCP lease time in seconds.

- sudo nano /etc/default/udhcpd *update konfigurasi default udhcpd
rubah DHCP enable jadi YES

DHCPD_ENABLED="no" --> DHCPD_ENABLED="yes"

- sudo nano /etc/network/interfaces *update konfigurasi wlan0

allow-hotplug wlan0
auto wlan0
iface wlan0 inet static
address 192.168.48.1
netmask 255.255.255.0

dan comment section ini

#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
#iface default inet manual

- sudo nano /etc/hostapd/hostapd.conf *konfigurasi nama SSID, password AP
dengan password WPA2

interface=wlan0
driver=nl80211
ssid=r48pi
hw_mode=g
channel=11
wpa=2
wpa_passphrase=p48sword
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
wpa_ptk_rekey=600
macaddr_acl=0

 open network *not tested

interface=wlan0
driver=nl80211
ssid=r48pi
channel=11
hw_mode=g
channel=6
auth_algs=1
wmm_enabled=0

- sudo nano /etc/default/hostapd *update konfigurasi hostapd

DAEMON_CONF="" --> DAEMON_CONF="/etc/hostapd/hostapd.conf"

- sudo nano /etc/sysctl.conf *update konfigurasi NAT
tambahkan line

net.ipv4.ip_forward=1

- sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
- sudo iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT *forward eth0 -> wlan0
- sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT *run
- sudo sh -c "iptables-save > /etc/iptables.ipv4.nat" *save iptables change
- sudo nano /etc/network/interfaces *update konfigurasi interface
tambahkan line
up iptables-restore < /etc/iptables.ipv4.nat
- sudo service hostapd start *run hostapd
- sudo service udhcpd start *run udhcpd
- sudo update-rc.d hostapd enable *run hostapd at boot
- sudo update-rc.d udhcpd enable *run hostapd at boot
- enjoy
