在我公司的网络中,我正在安装新的cisco2811路由器,但我有问题,我的局域网网络不能平和接入网络。我从ISP那里得到了点到点的互联网。
PTP IP为192.186.86.200/24,其开关端口为15。
局域网IP 172.16.16.200/24 DHCP。
我已经在路由器中配置了虚拟接口。
也实施了NAT规则,但我现在不知道如何访问互联网。
我的互联网IP是192.186.86.200/24。
我想我需要配置NAT规则,但不知道哪种类型。
这是路由器配置:

欢迎来到网络工程!这里有一些不对劲的地方:
如果希望外部主机连接到内部主机(如web服务器),则需要一个不同的NAT语句,但需要提供更多信息才能推荐配置。

将ISP分配的公共ip地址配置为路由器出口interfàce。并进一步配置用于互联网接入(出站流量)的端口地址转换(PAT)。
静态NAT一对1用于入站流量
For PAT配置
Router(config) # access-list 10 permit 172.16.16.0 0.0.0.0.255 any
Router(config) # ip nat inside source list 1 interfàce F0/1 overload
