Hi all,

Am hoping someone can help with this issue here. I have recently picked up a new Cisco 857w ADSL modem/router and am having some difficulties connecting to the internet.

I've configured it and it looks as though it connected as I can ping various URLs fron the CLI, however for some reason I am unable to ping anything from any computers which are connected to any of the ethernet ports.

DHCP seems to configured ok as I get a correct IP address and default gateway and dns server addresses are listed when doing an ipconfig on the computer. When I try to ping, I get no responses either by pinging URLs or IP addresses. When tyring to ping a URL, it does not even resolve to an IP address.

Below is the running config for the router. Can anyone advise where Im going wrong?

missing a nat statement
go in to configuration mode
then

int vlan 1
ip nat inside
ip nat inside source list 101 interface Dialer1 overload
access-list 101 permit ip any any

check whether you are able to ping hosts in the LAN.


default-gateway 10.10.10.1    configuration  is wrong.
the hosts will have default gateway as 10.10.10.1 and the router should get DG from ISP.
