no shutdown
exit 
```
__Porta da internet__:
```
configure terminal
interface gigabitethernet 0/1
ip address 172.16.1.69 255.255.255.0
no shutdown
exit 
```

## 2) Default routers 

### 2.1) Terminal

ip nat inside
exit

interface gigabitethernet 0/1
ip address 172.16.1.69 255.255.255.0
no shutdown
ip nat outside
exit

ip nat pool ovrld 172.16.1.69 172.16.1.69 prefix 24

access-list 1 permit 172.16.60.0 0.0.0.7
access-list 1 permit 172.16.61.0 0.0.0.7

ip route 0.0.0.0 0.0.0.0 172.16.1.254
