Iptables 运行错误

今天在一个4kec的环境上运行IPTABLES,遇到下面的错误:

 

 
root@UTS:~# iptables -L
modprobe: cannot parse modules.dep
iptables v1.2.8: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded. 

最后发现是Linux 内核配置的问题。
按照网上的建议,启动了下面的配置选项:(主要是IP: Netfilter Configuration这个目录下的一些配置)

 
编译内核选项 make menuconfig

主要是要注意选择block device的RAM disk 支持和network里的ipfilter支持,brige桥接支持,ebtable 的ip filter 相应的scsi卡驱动、网卡驱动、ext2 ext3 /proc /dev/pty等
