pinging outside network

[onel.riveron]

Hello everyone,

I apologize if I am asking a repeat question. Please help me with this network I designed. The router with the blue X in the picture can ping the cloud. But what do I need  to be able to ping from the routers with the red X to the cloud?

Currently all routers can ping each other, but only the one with the blue X can ping the cloud.

Hi, Check your routing. Does the failing router have a route to the cloud? Thanks John

Hello

1) do the red routers have knowledge of the cloud network 

2) does the cloud network have knowledge of the red routers networks

Are you referring to a routing protocol rip ospf etc.. ?
I'm using RIPv2, it's done on all the routers.

Hello,

the interface connecting R2 with the cloud, FastEthernet3/0, has IP address 10.3.3.48. What mask does this IP address have, and how are you advertising it ? The link between R1 and R6 has 10.3.3.0/24, make sure this is not the same network as the one configured on R2. I would suggest to change the IP address of FastEthernet3/0 on R2 to something you are not using yet, e.g. 10.8.8.1/24, and the IP address of the cloud to 10.8.8.2/24.

I figured it out. Needed to setup NAT on Router R2.

I'm using RIP to advertise.

Here's my conf:
