为了在实施 Cisco PIX 安全设备版本 7.0 时最大程度地提高安全性,在使用nat-control、nat、global、static、access-list 和 access-group 命令时,必须了解数据包在安全性较高的接口和安全性较低的接口之间的传递方式。本文档说明这些命令之间的差异,以及如何使用命令行界面或自适应安全设备管理器 (...

配置基本NAT 只需要一条命令:把私有 IP 地址转换成公网 IP 地址,在接口视图下配置 nat static global global-address inside host-address 命令。默认路由是网关路由器上的常见配置。使用 display nat static 命令查看 RT 上的静态 NAT 配置。 在PC 上验证联网功能。 抓包查看NAT 转换效果。分别抓包 RT 的内网口...
In the PAT configuration examples shown in this document, if an outside host tries to connect to the global address, it can be used by thousands of inside hosts. Thestaticcommand creates a one-to-one mapping. Theaccess-listcommand defines what type of connection is allowed to an inside hos...
inside global(内部全局地址)：私有主机在非自有网络中使用的地址，通常情况下inside global地址是从合法的全球统一可寻址空间中分配的地址，也就是通常所说的共有IP。inside global地址的特点是只会出现在非自有网络中并且一定是给私有主机使用的。outside local(外部本地地址)：非私有主机在自有网络内表现出来的IP...
Static NAT configuration requires three steps: - Define IP address mapping Define inside local interface Define inside global interface Since static NAT use manual translation, we have to map each inside local IP address (which needs a translation) with inside global IP address. Following command is...
For incoming messages, NAT changes the inside global IP address 130.1.100.10 to the inside local IP address 172.16.10.2 and the outside global IP address 140.1.1.2 to the outside local IP address 26.26.26.26. cumulus@switch:~$ net add nat static snat icmp 172.16.10.2 translate 130.1.100.100...
