Static routing problem

[johnpaulohernaez]

Hello everyone, I'm trying to follow a tutorial about static routing. Whenever I put my next hop from ISP router to Core Router which is 200.200.200.2 all I get is an error or failed. But when I went to my Core and setup a next hop for my Border router to 200.200.200.6 I'm having a successful PDU. Is there anything wrong in my ISP router? I hope you guys can help me. The tutorial im following is this one ("static routing with Connecting 4 routers with explanation | Cisco Packet Tracer Tutorial 3 - YouTube "). And I'm currently at the 15 minutes of the video that I'm having trouble with.

Hi

 Just setup a static route on the ISP and all good.

ISP#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ISP(config)#ip route 0.0.0.0 0.0.0.0 200.200.200.2
ISP(config)#

How did you do that?

Hello, sir. I tried using this but I still can't ping my other PC on 192.168.1.0 ; 192.168.2.0 network from my PC on the 192.168.0.0 network.

The Access list is blocking. You dont need the static route actually You have RIP configured and this enough 

 Just change RIP to version 2

router rip 

Version 2

Then, take off the Access list and Ping will work

Is there any solution wherein I can keep the NAT overload and not delete the access list and still ping all my devices with each other, sir? In this activity I'm given 2 tasks. Create a NAT overload then second is to be able to ping each pc. 

[Flavio Miranda]

Sure thing. But, for NAT overload, you dont need that Access List applied on the interface:

NAT is formed by:

ip nat inside

ip nat outside

access-list

nat pool

 Try to follow this guide.

!
interface GigabitEthernet0/0
ip address 192.168.0.254 255.255.255.0
ip nat inside
duplex auto
speed auto
!

!
interface Serial0/0/0
ip address 200.200.200.1 255.255.255.252
ip nat outside
!

access-list 1 permit 192.168.0.0 0.0.0.255

ip nat pool MY_POOL 200.200.200.1 200.200.200.2 netmask 255.255.255.0

ip nat inside source list 1 pool MY_POOL
