实验背景
某写字楼备搭建一张网络供楼内企业办公使用。写字楼共6层，目前已有三层投入使用，分别
是一层会客大厅、二层行政部及总经理办公室、三层研发部和市场部。一层设有核心机房，其
他各楼层均有一个小房间放置网络设备。
第一步
询问需求
第二步
按照需求组建方案
第三步 规划网络 总体流量

nat address-group 1 192.168.199.51 192.168.199.60 分配的地址（这个因为是vmware转换 随意 我使用了私网地址 ） 资源池不可以包含端口得IP得地址
配置端口
interface GigabitEthernet0/0/0 出口端口
ip address 192.168.199.50 255.255.255.0
nat server protocol tcp global current-interface 8080 inside 192.168.100.1 www
解释命令
这个命令是配置网络地址转换（NAT）服务器的规则，用于将外部TCP流量映射到内部地址上的WWW服务。具体解释如下：
nat server：表示配置一个NAT服务器规则。protocol tcp：指定该NAT规则适用于TCP协议的流量。global current-interface 8080：表示将流量从当前接口（可能是外部接口）上的8080端口进行匹配。inside 192.168.100.1 www：将匹配到的流量映射到内部地址192.168.100.1上的WWW服务。
这个命令的作用是允许外部网络通过NAT服务器访问内部地址192.168.100.1上的WWW服务，并且使用8080端口进行通信
nat outbound 2000 address-group 1
int g0/0/1 入口
ip add 192.168.204.1 255.255.255.252

rule 5 deny ip source 192.168.105.0 0.0.0.255 destination 192.168.0.0 0.0.255.255
这条规则阻止了从192.168.105.0/24网段向192.168.0.0/16网段的所有流量
