8.解决网页断流现象
网页断流，就是说内网TCP传输具有时效性，不能保存过久，包一多路由就负担了，太短就是变连接不上了。游戏的TCP包就不存在这样的问题，因为游戏包小，时时通信，即使被刷新失效，马上也会有的。
网页就不一样的了，有时候发现网页打不开，其它都正常这个就叫网页断流
网页断流几个关系的问题：
8.1.tracking问题
使用本站提供的，保证无问题，一个SYN推荐大家调高一点点为好
/ ip firewall connection tracking
set enabled=yes tcp-syn-sent-timeout=5s tcp-syn-received-timeout=30s \
tcp-established-timeout=5d tcp-fin-wait-timeout=2m \
tcp-close-wait-timeout=1m tcp-last-ack-timeout=30s \
tcp-time-wait-timeout=2m tcp-close-timeout=10s udp-timeout=30s \
udp-stream-timeout=3m icmp-timeout=30s generic-timeout=10m
ip firewall connection tracking 的图
8.2.防火墙问题 防火墙把TCP3129-3198给禁用了 删除31XX一系列规则
8.3.Queue Tree 限制线程问题
这里说明下，我们只限制速度，不限制线程数为好 haohao 看晕了 哈哈 看不懂要
