ASA的twice-nat将互联网访问的源地址转换为内网接口地址测试

一.测试拓扑二.测试思路不考虑网络拓扑的合理性，只是考虑网络是否可通外网访问内部服务器在防火墙上映射的公网地址不通是因为R1的默认路由指向的不是防火墙，出现了非对称路由问题，导致TCP连接来回路径不一致而会话失败如果把外网访问内部服务器的源地址转换为防火墙内网接口地址，则不会出现非对称路由问题三.基本配置路由器Server： interface FastEt...

利用ASA的Twice NAT解决内网无法访问映射后的公网地址

一.概述：默认情况下，不管是Inside还是DMZ区映射到Outside区的地址或服务，Inside和DMZ区都无法通过映射后地址来访问内部服务器。ASA8.3版本之后有一种新的NAT叫Twice-NAT,它可以在一个NAT语句中既匹配源地址，又匹配目标地址，并且可以对源地址、目标地址，端口号，三个参数中一~三个参数的转换。二.基本思路： A.Inside区映射到Ou...
