下面回到路由器，编辑wifidog.conf，一般情况下，我们之后配置ExternalInterface，GatewayInterface和AuthServer这三项就可以，其他默认。下面是我的配置：

opk安装包：luci-app-wifidog-all.ipk

# $Id$
# WiFiDog Configuration file# Parameter: GatewayID
# Default: default
# Optional
#
# Set this to the node ID on the auth server
# This is used to give a customized login page to the clients and for
# monitoring/statistics purpose. If you run multiple gateways on the same
# machine each gateway needs to have a different gateway id.
# If none is supplied, the mac address of the GatewayInterface interface will be used,
# without the : separators# GatewayID default# Parameter: ExternalInterface
# Default: NONE
# Optional
#
# Set this to the external interface (the one going out to the Inernet or your larger LAN).  
# Typically vlan1 for OpenWrt, and eth0 or ppp0 otherwise,
# Normally autodetectedExternalInterface eth1# Parameter: GatewayInterface
# Default: NONE
# Mandatory
#
# Set this to the internal interface (typically your wifi interface).    
# Typically br-lan for Openwrt (by default the wifi interface is bridged with wired lan in openwrt)
# and eth1, wlan0, ath0, etc. otherwise
# You can get this interface with the ifconfig command and finding your wifi interfaceGatewayInterface br-lan# Parameter: GatewayAddress
# Default: Find it from GatewayInterface

# Set this to the internal IP address of the gateway.  Not normally required.GatewayAddress 192.168.1.1# Parameter: HtmlMessageFile
# Default: wifidog-msg.html
# Optional
#
# This allows you to specify a custome HTML file which will be used for

# used inside the file will be replaced.
#
# HtmlMessageFile /opt/wifidog/etc/wifidog-.html# Parameter: AuthServer
# Default: NONE
# Mandatory, repeatable
#
# This allows you to configure your auth server(s).  Each one will be tried in order, untill one responds.
# Set this to the hostname or IP of your auth server(s), the path where
# WiFiDog-auth resides in and the port it listens on.

# Default: 60
# Optional
#
# How many seconds should we wait between timeout checks.  This is also
# how often the gateway will ping the auth server and how often it will
# update the traffic counters on the auth server.  Setting this too low
# wastes bandwidth, setting this too high will cause the gateway to take 
# a long time to switch to it's backup auth server(s).# CheckInterval 60# Parameter: ClientTimeout
