Cisco 2811 Home Lab Setup Basic Routing

eth0_dredd

Level 1

Greetings everyone. 

 

I am close to taking my CCNA and bought a Cisco 2811 router to test. I have read many threads here and tried many tutorials. For some reason I can't this router to route requests to the web. I can ping the dns server and google.com outside from the router itself, but not from the hosts connected to the router on the internal network. The most relevant thread is here and this is how I have set things up. https://community.cisco.com/t5/routing/home-lab-assistance/td-p/3218838

 

Int f0/0 - Internal network 10.1.0.1

Setup as DHCP server to give addresses starting at 10.1.0.50 with the router itself as the default router*

 

Int f0/1 - connected to switch > connected to third switch which goes to internet at 192.168.1.1

Configured to get address from home router DHCP *192.168.1.102

 

I have a default route set (i think) to send all internet traffic to the external router with internet.

ip route 0.0.0.0 0.0.0.0 192.168.1.1

 

Following this I set up nat with access list and put the interfaces as inside/outside

interface FastEthernet0/0
ip nat inside
interface FastEthernet0/1
ip nat outside

ip nat inside source list ACLIST interface FastEthernet0/1 overload

ip access-list standard ACLIST
permit 10.0.0.0 0.0.0.255

 

I have attached the running config. The host computer on the inside gets its DHCP address just fine and can ping both interfaces on the router but not the outside internet or the routers gateway at 192.168.1.1.

 

Appreciate any help in what should be a very simple task.

Hi @eth0_dredd 

 

Try this change:

 

ip access-list standard ACLIST
permit 10.1.0.0 0.0.0.255 <--your network is 10.1.0.0/24
