Hello all, I am new at configuring routers (just finished CCNA classes) and have had my instructor look over my configuration and even let my instructor take home my router to see that it worked at his home and it does. It seems to be able to connect to the ISP because it does assign it an IP address but I am not able to get on the internet. I will post my config info for evaluation plus other read outs that I have taken. Any help would be great.

Type ipconfig on the computer and check if you are getting an ip address and dns server addresses on the computer. Check with yopur ISP if you dont get an ip address or DNS server address. Check if you are able to ping the DNS servers. Check for firewall and antivirus on your computer . Disable them for the time being.

Thanks for the reply I didn't think anyone was going to respond. =) I am sorry but I posted a similar link in the "LAN, Switching and Routing:" section of these forums.
Q: Type ipconfig on the computer and check if you are getting an ip address and dns server addresses on the computer
A: I did ipconfig on my workstation and I get proper IP address for LAN (192.168.xxx.xxx) and I get proper DNS address for Verizon. Primary DNS 1: 68.238.64.12 Secondary DNS 2: 68.238.128.12
Q: Check if you are able to ping the DNS servers.
A: I am not able to ping the DNS's from my workstation or the con 0 connection from my server for some reason. But I am able to ping the assigned address to the Routers ADSL WAN connection (71.105.142.101) the Router LAN (192.168.xxx.xxx) and the workstation (192.168.xxx.xxx) from the workstation ethernet or the servers con 0 or ethernet
Note* Server is just local file server not required for internet access.
Q: Check for firewall and antivirus on your computer
A: They are disabled/not Installed. Don't use winxp sp2 firewall and AVG is only antivirus I have but it is disabled/not Installed.

I entered the information you suggested but it is still not working. The following is a copy of the current running config now. I hope they are setup right.

Hi,
please configure:
interface ATM0
no pvc 0/35
no bridge-group 1
interface ATM0.1 point-to-point
pvc 0/35
bridge-group 1
Then, from router, can you ping 4.2.2.1 ?
11-15-2007 08:05 PM
I appreciate the help. I edited the script as per your instructions and I was not able to connect but, I did notice a difference in the way the ADSL obtained it's address from Verizon. The old configuration I had it was only a second or two before I was able to obtain IP from Verizons network. Once I edited with you suggestions, I obtained an address but it took about 1hr. to an 1 1/2 hrs before I was able to get an IP.
11-23-2007 09:58 AM
Does anyone have any other suggestions that may help??
11-23-2007 10:01 AM
Can you send the revised configuration and output of "show ip int brief" ?
11-23-2007 11:50 AM
I am going to have to hook up the router again to the DSL connection. Upon doing so I will get the info your are requesting but it may take a few hours to get back online seeing as it takes so long for my linksys to pull an ip again after.

*UPDATE** I did "sh ip int brie" before the interface got an ip and just after it got assigned an IP as you can see at the end but I was still not able to ping any addresses outside except 71.105.225.181

Please configure "ip route 0.0.0.0 0.0.0.0 dhcp".
Failing that, please send config again.
