iptables支持多less条规则?

最近有人问我,我没有答案。 我知道这是一个开放式的问题,但是你可以在表/链中安装规则的数量是否有限制? 如果是这样,我怎么能find它? 我想这将在不同的机器上有所不同。

Jan Engelhardt引用

 The theoretical upper limit of maximum number of rules for a 32-bit environment would be somewhere around 38 million, but you could also construct a rule that is so crowded with matches that even it won't fit, so the lower limit of max rules is 0.

根据linuxquestions.org ,在32位机器上,IPTables将支持大约25,000条规则。 除此之外,特别是从27,000,事情开始变得片状。
