浅析ACL与NAT的执行顺序

Analysis of the ACL and NAT execution order

ACL和NAT作为常用的两种网络技术,经常会被同时应用在网络中的同一个位置,这时就必须要考虑到两者的执行顺序。执行顺序上的差异将直接影响到ACL的配置和应用的有效性。通过对主流的两大设备厂商的设备进行实验测试,了解不同厂商对ACL和NAT执行顺序处理上的差异,从而确保网络管理员能够对于不同厂商设备给出正确的ACL约束规则,保护网络的安全。

ACL and NAT as the common two kinds of network technology, often be used at the same time in the network in the same location, then it is necessary to consider both execution sequence. Executive order differences will directly affect the ACL configuration and application of. Based on the mainstream of the two major equipment manufacturers of equipment test, understand the different manufacturers on the ACL and NAT execution order processing differences, thereby ensuring that the network administrator to different equipment manufacturers provide the correct ACL rules, protect network security.
