OpenWrt Wi-Fi client mode

OpenWrt settings

Under OpenWrt The main is to set the/etc/config/network,/etc/config/wireless these two files, the other is the default LAN and WAN mode.

/etc/config/network, turn off the VLAN (enable_valn=0), set the LAN interface to static and remove the bridge (the default is ' option Type bridge ', WiFi is usually automatically bridged to the LAN interface), The WAN removes the ' option ifname ' option (the wireless WiFi interface automatically joins the WAN as the ifname).

Once configured, the interfaces on all switches become internal LANs, while wireless WiFi is used as a WAN connection extranet. The LAN and WAN are NAT-mode address translation (specifically in the firewall WAN settings masq=1, the default is set), firewall Nat option is called Masquerade (camouflage), is the WAN interface packet Source address of the network to disguise their own, Very image:).

Make sure the firewall boot up:

/etc/init.d/firewall Enable

To see if Firewall is started:

/etc/init.d/firewall enabled && Echo on

    /etc/config/wireless, set WiFi parameters:
