netstat -r查看一下路由，default的gateway对不对

kinux

把你的/etc/rc.conf, /var/run/dmesg.boot, netstat -r, ifconfig -a, 全部都貼出來...

在demsg.boot中如下几行：

em0: <Intel(R) PRO/1000 Network Connection, Version - 1.4.10>; port 0xdc00-0xdc1f mem 0xfea00000-0xfea1ffff,0xfeb00000-0xfeb1ffff irq 5 at device 2.0 on pci2

兄台有没有办法帮俺一把？

netmask 255.255.252.0

其它机子也用这个掩码？

没错，
其实刚开始网络都是正常的，后来我安装好了sendmail，接着安装ipop3d出错提示cclient out of date，后面不知咋的网络就翘了，重装几次系统一样出错
