手机终端在Portal环境下弹出页面慢优化经验案例

手机在连接我司无线网络，V7 AC上启用Portal时，反馈手机终端弹出页面慢

无

IOS，安卓终端有自己的判断逻辑，一般来说都是根据到网站的连通性来判断是否弹页面，根据此原理进行优化，但是由于IOS处理逻辑的原因，IOS终端首次连接Portal网络等待几十秒这个过程目前没有办法优化，该优化针对的是非首次关联弹出页面慢的情况。

首先Portal正常配置，另外添加如下配置，并按照注释进行修改；

#

portal host-check enable

//按照现场DNS配置

portal free-rule 1 destination ip 114.114.114.114 255.255.255.255

portal free-rule 2 destination ip any udp 53

portal free-rule 3 destination ip any tcp 53

portal free-rule 4 destination ip any tcp 5223

//如果没有微信认证可以不放通微信

portal free-rule 10 destination short.weixin.qq.com

portal free-rule 11 destination mp.weixin.qq.com

portal free-rule 12 destination long.weixin.qq.com

portal free-rule 13 destination dns.weixin.qq.com

portal free-rule 19 destination isdspeed.qq.com

portal free-rule 20 destination ***.***
