mangle 表
mangle:
This table is used for specialized packet alteration. Until
kernel 2.4.17 it had two built-in chains: PREROUTING (for
altering incoming packets before routing) and OUTPUT (for
altering locally-generated packets before routing). Since
kernel 2.4.18, three other built-in chains are also sup-
ported: INPUT (for packets coming into the box itself), FOR-
WARD (for altering packets being routed through the box),
and POSTROUTING (for altering packets as they are about to
go out).
发现大家使用mangle表的比较少。
一般情况,在什么状况下才使用mangles呢??

关于mangle的确很少见用.用的比较高当:
允许通过改变包的内容进一步"纠正"包.例如此表可以对包进行整形,使之为特定的VPN客户备用.
链名:PREROUTING,POSTROUTING,OUTPUT,INPUT,FORWARD.
可使用的目标动作:TTL,TOS,MARK
