CCNA实验–NAT和PAT的配置

KC-R1(config)# ip nat pool kachy 173.16.1.58 173.16.1.126 netmask 255.255.255.0 #创建地址池

KC-R1(config)#access-list 1 permit 10.1.1.0 0.0.0.255 #创建ACL

KC-R1(config)#ip nat inside source list 1 pool kachy #二者关联

KC-R1(config)#exit

Ping测试

PC-1#ping 202.101.1.149 #测试证明能通

Success rate is 100 percent (5/5), round-trip min/avg/max = 96/125/148 ms

PC-1#telnet 202.101.1.149 #测试证明能远程连接

Trying 202.101.1.149 … Open
