摘　　要：使用NAT可缓解IP地址的不足,但导致了内网地址和外网地址不一致,并且因地址转换信息未保存而带来了网络行为不可审计和追踪.本文阐述了一种可行的NAT日志的保存方案,即采用在线精简和压缩的方法将海量日志数据保存为压缩文件,亦可将日志保存到数据库中.该方案在实际运行中效果良好.Use of NAT alleviates the IP address shortage; however, it results in the inconsistencies between internal network address and the external network address, which brings about the non-auditability and non-trackability of the network behavior due to being unable to save the address translation information. This paper describes a solution of storing NAT log that uses online downsizing and compressing to save the massive log data to compressed files or store them into database. This solution works well in practice.
