带宽带宽限制

如果是server发起去client的连接不受上面配置的限制.
[Eudemon-zone-untrust]statisticcaripoutbound2acl2000指定从untrust域来的特定IP发起的会话的总带宽等级为2,指该IP发起的会话的双向流量之和.
比如,如果untrust域穿过防火墙访问WWW服务器,则该会话中去服务器的流量加上WWW服务器回来的流量之和,不会超过设定的带宽等级.
如果服务器是FTP,因为服务器的Port方式下载,其FTP数据通道是由服务器发起,应增加如下配置[Eudemon-zone-untrust]statisticcaripinbound2acl2000才能够限制住该用户的FTP下载流量.
注:IPCAR中限制的流量,只包含IP包载荷,不包含二层头.
