Cisco 877 Config
Having trouble configuring a Cisco 877 for a bigpond ADSL2. I am getting Carrier Detect and the ATM0 interface seems to be connecting but cannot ping any addresses or load web pages. Running Config is:
ip dhcp pool LAN_CLIENTS
network 10.1.1.0 255.255.255.0
default-router 10.1.1.1

I honestly do see anything wrong with what you have posted. Can you post the entire config?
I meant I don't see anything wrong.

Thanks for the comments. As you can see from the config I have enabled NAT. I tried to use SDM first but I could not edit the interfaces after creating them and was having trouble with the dynamic ip address on the dialer interface.

Where are you pinging from?
Have you verified that you can ping from the router to a public address?

The router cannot currently ping any external addresses. It did before but I started again because it was not working properly.
I will have access to the router again this afternoon. I will try your changes Soulja. What is the syntax?

Ok now the router can ping external IP addresses but the clients cant ping the cisco. If I connect my laptop directly to the cisco it still says media disconnected. All the interfaces are up.
Post output of "show int status" and "show ip int brief"
ASKER
I reconfigured from scratch using an older template I had and all is working fine now. Think I must have missed some random line. The interfaces were all up and ok. Just couldn't ping from a client.
Compare your old template and the config above with Diffmerge or something similar.
ASKER
Think I stuffed up the VLAN interface.
Thanks for the help guys!
