不同VLAN里共享代理服务器的问题

yangjiushan

各位大虾：下面的拓扑结构图，我上网的代理服务器是放在VLAN11 里的，在我们局域网里的IP地址为：192.168.4.2。掩码为：255.255.255.0。网关为:192.168.4.254。在同一VLAN下的主机上网时断时续，很不稳定，在另外一个VLAN里的主机跟本上不了。
在没有上这台交换机之前，我们大家都处在同一广播域里(就是全是用“傻瓜型”二层交换机联网)，现在划分VLAN了，不在服务器这个VLAN里主机就上不了网。
但是大家都能PING通服务器，而且都设置了代理服务器的地址。请大家教我，为什么，怎样设置？？？？？

还有就是服务器经常重启，出现下面的错误提示！！！

把config show出来看看

各位，还有就是：在一个VLAN里我们有两条线上网，一条是专线（有固定IP地址），另一条是ADSL自动拨号的

momo

先把ADSL去掉如何?

bingosek

ip route 0.0.0.0 0.0.0.0 Vlan10
ip route 0.0.0.0 0.0.0.0 Vlan11

这里怎么会这样设置呢?

路由做错了吧！

小N哥哥

再说你做这样多ＡＣＬ对交换机的响应很大！
