Cisco 837 & SDM Set Up (No Internet Connection)

reb999000
Level 1
Level 1

To All, 

I have recently installed SDM in order to access the internet with my 837 ADSL. I have configured the router's ethernet interface with ip address 10.10.10.1/24 (Default Gateway) and my PC to 10.10.10.2/24, I can both ping & telnet to the router from my PC, I also have pinged 8.8.8.8 on the router and that came up to 100%.

But I am not getting the internet, I will show any configs from the router & post these for further information.

I appricate any help with this issue

Regards,

Bob.

Hi,

Now at least you should be able to ping 8.8.8.8 from a host in your LAN, is this the case ?

If you can't browse it is because you have no dns server in your dhcp poo and your router which is doing proxy dns has got the wrong server:

no ip name-server 10.10.10.1

ip name-server 8.8.8.8      You should replace by your ISP name servers but for now it will do the trick

ip dhcp pool DSLR

dns-server 10.10.10.1

Regards.

Hi,

ip nat inside source list 1 interface Dialer0 overload

You're missing this:  access-list 1 permit 10.10.10.0 0.0.0.255

I have configured the above Acess List command and "copy run start" and I am afraid no joy, here is the current configuation from "show ip int brief":
