Help me make my GNS3 topology talk to the internet

Level 1

Anyone with experience on this one, please help.

 

I have a GNS3 topology and I can't seem to get it to talk to the internet.

The cloud is configured with my computer's NIC and every router in the topology can ping the NIC

 

I have configured NAT.

I'm advertising with RIPv2.

ip domain-lookup is enabled.

 

What might I be missing or have not configured?

 

 

Router's config:

 

 

R2#sh run

Hello,

 

try and change your configuration as below:

 

ip route 0.0.0.0 0.0.0.0 FastEthernet3/0
!
ip nat inside source list 1 interface FastEthernet3/0 overload
!
access-list 1 permit 10.1.1.0 0.0.0.255
access-list 1 permit 10.2.2.0 0.0.0.255
access-list 1 permit 10.7.7.0 0.0.0.255

Tried it, but no go.

I can ping my real network gateway and other devices in it, just not out to the internet. 

Hello,

 

what is the IP address of your real default gateway ? What is your cloud connected to ?

 

interface FastEthernet3/0
ip address 10.10.1.48 255.255.255.0
ip nat outside
duplex full

 

The real default gateway should be on the same subnet as your FastEthernet3/0.
