cisco2821+cisco3750 出现QQ频繁掉线的现象

cui6522123

我公司现在使用的是cisco2821路由器，版本的12.4(22)T和cisco的3750G核心交换机，版本12.2(35)SE5.\r\n\r\n现在配置好后出现的问题是QQ总是频繁掉线，但其他的IM软件不会掉线，网页浏览页正常。就是不知道是哪里出现问题了，以前用的netgare的防火墙没有这样的现象。刚刚更换的设备就出现，不知道是不是配置的问题，请大家帮忙分析分析，需要配置的话   我稍后会贴出来！

ip virtual-reassembly  去掉试试\r\n\r\nip nat translation timeout 500 改大一点\r\n\r\n那个4001-4999端口DENY的先去掉。
