can't initialize iptables table `nat': Table does not exist

第一种

如果说nat名字是大写的NAT 试试iptables -tnat -L

原因是如果使用命令iptables -tNAT -L 是没有NAT表的也会出现这个错误

第二种：
该错误完整应该是这样的：

can‘t initialize iptables table `nat‘: Table does not exist (do you need to insmod?)

Perhaps iptables or your kernel needs to be upgraded.

首先

[[email protected] ~]# modprobe -l|grep iptable_nat

kernel/net/ipv4/netfilter/iptable_nat.ko

[[email protected] ~]#

尝试如下操作

[[email protected] ~]# modinfo iptable_nat

filename:       /lib/modules/2.6.32-431.el6.x86_64/kernel/net/ipv4/netfilter/iptable_nat.ko

alias:          ip_nat

license:        GPL

srcversion:     507BCAD1E3A207FDF875EEC

depends:        ip_tables,nf_conntrack_ipv4,nf_nat,nf_conntrack

vermagic:       2.6.32-431.el6.x86_64 SMP mod_unload modversions

[[email protected] ~]# insmod /lib/modules/2.6.32-431.el6.x86_64/kernel/net/ipv4/netfilter/iptable_nat.ko

insmod:error inserting ‘iptable_nat.ko‘:-1 unknown symbol in module

[[email protected] ~]# modprobe iptable_nat

[[email protected] ~]#

即可

第三种情况：

[[email protected] ~]# ll  /lib/modules/

total 4

drwxr-xr-x. 8 root root 4096 Mar  7 11:11 2.6.32-431.el6.x86_64

[[email protected] ~]#

[[email protected] ~]# uname -r

2.6.32-431.el6.x86_64

[[email protected] ~]#

是否本地的kernel 的模块和kernel相对应   多出现的原因为 升级过内核。。 但是本地还是老版本的模块  安装当前kernel 的包即可
