NAT

Question 1

static NAT

Answer 1

(config)# int fa0/1
(config-if)# ip address 10.1.1.1 255.255.255.0
(config-if)# ip nat inside

(config)# int fa0/2
(config-if)# ip address 170.46.2.2 255.255.255.0
(config-if)# ip nat outside

ip nat inside source static 10.1.1.1 170.46.2.2

Question 2

dynamic NAT

Answer 2

(config)# int Ethernet0
(config-if)# ip address 10.1.1.10 255.255.255.0
(config-if)# ip nat inside

(config)# int Serial0
(config-if)# ip address 170.168.2.1 255.255.255.0
(config-if)# ip nat outside

ip nat pool TODD 170.168.2.3 170.168.2.254 netmask 255.255.255.0

access-list 1 permit 10.1.1.0 0.0.0.255

ip nat inside source list 1 pool TODD

Question 3

PAT

Answer 3

(config)# int Ethernet0
(config-if)# ip address 10.1.1.10 255.255.255.0
(config-if)# ip nat inside

(config)# int Serial0
(config-if)# ip address 170.168.2.1 255.255.255.0
(config-if)# ip nat outside

ip nat pool globalnet 170.168.2.1 170.168.2.21 netmask 255.255.255.0

access-list 1 permit 10.1.1.0 0.0.0.255

ip nat inside source list 1 pool globalnet overload
