create your hostapd.conf: "vim /etc/hostapd/hostapd.conf "
hostapd.conf (236 字节)
-
According to your network interface(can search internet) to config ap0:
my network interface which can search internet is wan, and ip is 192.168.30.102, so I config ap0 as follows:
“ifconfig ap0 192.168.30.188 netmask 255.255.255.0”
-
Run hostapd : “hostapd -d /etc/hostapd/hostapd.conf”
-
Config dhcp file : “vim /etc/dhcp/dhcpd.conf”
subnet 192.168.30.0 netmask 255.255.255.0 {
range 192.168.30.2 192.168.30.250;
option domain-name-servers 8.8.8.8;
option routers 192.168.30.1;
} -
Config dhcp of ap0, then the devices which connect ap0 could get IP: "dhcpd ap0 -pf /var/run/dhcpd.pid "
-
And a bridge
brctl addbr br0
brctl addif br0 ap0
brctl addif br wan
-
Config br0 : “ifconfig br0 192.168.30.180 netmask 255.255.255.0”
-
Add br0 gw as : “route add -net default netmask 255.255.255.0 gw 192.168.30.1 dev br0”
