routeros之hotspot设置
参照routeros的手册，针对我的情况作了部分修改。已经在2.7.14和2.8.11上测试通过。

我的routeros是2块网卡，ether1连接adsl,做pppoe client，ether2连接局域网。
首先按照论坛上置顶的说明正确安装并配置routeros,实现客户机能够正常上网。
然后terminal routeros

改变www服务端口为8081：
/ip service set www port=8081

改变hotspot服务端口为80,为用户登录页面做准备：
/ip service set hotspot port=80


Setup hotspot profile to mark authenticated users with flow name "hs-auth":
/ip hotspot profile set default mark-flow="hs-auth" login-method=enabled-address

增加一个用户：
/ip hotspot user add name=user1 password=1


重定向所有未授权用户的tcp请求到hotspot服务
/ip firewall dst-nat add in-interface="ether2" flow="!hs-auth" protocol=tcp action=redirect
to-dst-port=80 comment="redirect unauthorized clients to hotspot service"


允许dns请求、icmp ping ；拒绝其他未经认证的所有请求：
/ip firewall add name=hotspot-temp comment="limit unauthorized hotspot clients"

/ip firewall rule forward add in-interface=ether2 action=jump
jump-target=hotspot-temp comment="limit access for unauthorized hotspot clients"

/ip firewall rule input add in-interface=ether2 dst-port=80 protocol=tcp
action=accept comment="accept requests for hotspot servlet"

/ip firewall rule input add in-interface=ether2 dst-port=67 protocol=udp
action=accept comment="accept requests for local DHCP server"

/ip firewall rule input add in-interface=ether2 action=jump
jump-target=hotspot-temp comment="limit access for unauthorized hotspot clients"

/ip firewall rule hotspot-temp add flow="hs-auth" action=return
comment="return if connection is authorized"

/ip firewall rule hotspot-temp add protocol=icmp action=return
comment="allow ping requests"

/ip firewall rule hotspot-temp add protocol=udp dst-port=53 action=return
comment="allow dns requests"

/ip firewall rule hotspot-temp add action=reject
comment="reject access for unauthorized clients"

创建hotspot通道给认证后的hotspot用户
Create hotspot chain for authorized hotspot clients:
/ip firewall add name=hotspot comment="account authorized hotspot clients"

Pass all through going traffic to hotspot chain:
/ip firewall rule forward add action=jump jump-target=hotspot
comment="account traffic for authorized hotspot clients"


客户机输入任何网址，都自动跳转到登陆页面，输入账号密码，继续浏览。
如果使用ftp、pop3等，也必须先通过网页登录，才可以使用，当然使用winbox的时候也必须先登录。
