Konfigurasi Wireless

Konfigurasi wireless dan mengaktifkan sebagai adhoc pada channel 1. 

vi /etc/config/wireless

Isinya kira-kira 

config wifi-device  radio0
        option type     mac80211
        option channel  1
        option hwmode   11g
        txpower         15
        option path     'platform/ar231x-wmac.0'  # option path berbeda untuk NS2 NSM2 Bullet dll

        # REMOVE THIS LINE TO ENABLE WIFI:
        option disabled 0

config wifi-iface
        option device   radio0
        option network  MESH
        option mode     adhoc
        option ssid     MESH
        option encryption none
        option bssid    02:CA:FF:EE:BA:BE


Konfigurasi IP address MESH

Set IP statik melalui perintah 

vi /etc/config/network

Isi kira-kira 

config interface loopback
        option ifname   lo
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0 

config interface lan
        option ifname   eth0
        option type     bridge
        option proto    static
        option ipaddr   192.168.1.1
        option netmask  255.255.255.0

# konfigurasi berikut penting untuk MESH
#
config interface 'MESH'
	option _orig_ifname 'wlan0'
	option _orig_bridge 'false'
	option proto 'static'
       option ipaddr   10.123.123.223 # (SETIAP NODE HARUS menggunakan IP yang BEDA!!)
       option netmask  255.0.0.0

Setup NAT melalui MESH

Sebaiknya buat setup Firewall 

rm /etc/config/firewall

Buat NAT di /etc/rc.local saja

Set agar NAT dan OLSR start waktu booting

Edit rc.local 

vi /etc/rc.local

Isi 

ifconfig wlan0 10.123.123.223 netmask 255.0.0.0 (IP ADDRESS sama dengan IP addres di /etc/config/network  di ATAS)
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
/etc/init.d/telnet stop
/etc/init.d/olsrd stop
olsrd -f /etc/olsrd.conf &

exit 0


Nampaknya NAT sebaiknya di aktifkan di rc.local. Semua setting /etc/config/firewall di matikan agar OLSR tidak rewel.

Buat file /etc/olsrd.conf

Edit 

vi /etc/olsrd.conf

Isi dengan 

# DebugLevel 0
# AllowNoInt yes
# IpVersion 4
# RtTable 111
# RtTableDefault 112

Hna4
{
# 0.0.0.0 0.0.0.0            # JIKA INGIN memberitahukan bahwa kita adalah gateway ke Internet
# 192.168.0.0 255.255.255.0  # JIKA INGIN memberitahukan kita gateway ke 192.168.0.0/24
}
