At first I wrote all the static routes , Later, I remembered that there was a default route , To use the default route, you only need to write some shorter paths as static paths to supplement

To configure dhcp

[r3]DHCP enable
[r3]ip pool a
[r3-ip-pool-a]network 192.168.1.96 mask 27
[r3-ip-pool-a]gateway-list 192.168.1.97
[r3-ip-pool-a]dns-list 114.114.114.114
[r3-ip-pool-a]q
[r3]int g 0/0/2
[r3-GigabitEthernet0/0/2]dhcp select global 
[r3-GigabitEthernet0/0/2]q

Access loopback 6

because R6 That one is the public network , All need to use EASY ip Implement many to one port mapping, plus the previous default path implementation
