Thanks for these uploads :)

Observacion: el ejercicio indica que debes utilizar las CUATRO direcciones disponibles en el espacio de direcciones 209.165.76.196/30. Con la mascara 255.255.255.252 solo se pueden utilizar 2 direcciones.

While the only language I know is english, watching your videos has really helped me grab the content. The relation between cause, effect and reason, while not in my own language is explained in the gestures. Thank you for all of your help.

Hello Christian. Very helpful video! Can I ask when we define the pool of four addresses (209.165.76.196 - 199) how do did we calculate the netmask? I mean why is 255.255.255.252 ?

Telecom Sat

profesor como se en que router debo configurar la NAT?

Vesko Dimitrov

Hey Chris how do you know that 209.165.76.199 is the end Ip address?

Eduardo Ricardez

Hola Christian, hay algo que no me queda muy claro, en pregunta: Observe que en la topología hay tres rangos de red que se traducirán según la ACL creada. ¿Qué sucede si más de dos dispositivos intentan acceder a Internet?..por qué un tercer dispositivo se denega? Si hay 4 Ip's publicas para que puedan traducir 4 Ip's privadas? el rango de Publicas es: 209.165.76.196-199/30 ? muchas gracias por tu tiempo.

Chris, my access-list was configured as
access-list acl 1 permit 172.16.0.0 0.0.255.255
ip nat pool NAT 209.165.76.196 209.165.76.199 netmask 255.255.255.252

One thing that was very strange. When I set mine up as you did with

IP nat inside source list 1 pool NAT it did not work.

It only worked when I used
ip nat inside source list 1 int s0/0/0
It showed:
Pro Inside global Inside local Outside local Outside global
tcp 209.165.76.193:1024172.16.10.2:1026 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.193:1026172.16.10.1:1026 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.193:1027172.16.11.1:1027 209.165.201.5:80 209.165.201.5:80

It then connected from each pc to the Server1. HOWEVER, when I look at sho ip nat trans, it shows that one of the inside global IPs that was used was off of R2 interface such as 209.165.76.193? ABOVE

I then removed the above line and put
ip nat inside source list 1 pool NAT overload
It showed:

Pro Inside global Inside local Outside local Outside global
tcp 209.165.76.193:1024172.16.10.2:1026 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.193:1026172.16.10.1:1026 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.193:1027172.16.11.1:1027 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.197:1027172.16.10.1:1027 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.197:1028172.16.10.2:1028 209.165.201.5:80 209.165.201.5:80
tcp 209.165.76.197:1029172.16.11.1:1029 209.165.201.5:80 209.165.201.5:80

Is there any reason why it would be using the actual IP address of s0/0/0 off R2 as part of the nat? Even if i used dynamic or tried to overload, it still includes the interface? Even with only giving it a certain pool of IP addresses?

Eduardo
