can't ping the internet

Hello,

I started a post earlier but after working on the problem some more, I realized that I was barking up the wrong tree.

I figured out how to add DGW and DNS addresses to my config but, telling my router where the DNS servers are does me no good if I can not even ping them.

Here is my config...

"Current configuration : 1440 bytes

!

version 12.2

no service pad

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

!

hostname 1605r

!

enable secret

!

ip subnet-zero

no ip source-route

ip name-server 64.81.45.2

ip name-server 216.231.41.2

!

no ip bootp server

!

!

!

!

interface Ethernet0

ip address 64.xxx.xxx.xxx 255.255.255.0

no ip proxy-arp

ip nat outside

no cdp enable

!

interface Ethernet1

ip address 192.168.1.1 255.255.255.0

no ip proxy-arp

ip nat inside

no cdp enable

!

ip default-gateway 64.xxx.xxx.xxx

ip nat inside source list 1 interface Ethernet0 overload

no ip classless

ip route 0.0.0.0 0.0.0.0 Ethernet0

no ip http server

!

access-list 1 permit 192.168.1.0 0.0.0.255

no cdp run

Now, this config worked perfectly on my cable modem where my isp assigned my ip address for int e0 dynamically. Now I have a new isp that has static addressing and I can't get it to work?!?!?

I entered the ip address and netmask on e0 and I can ping my DGW but I can not ping my dns servers. If i hook up a pc to my dsl modem instead of my router, I can surf fine.

Anyone know what I am missing?

Thanks, Chris

Chris,

Try enabling "ip classless"

you may also try "ip route 0.0.0.0 0.0.0.0 Ethernet0 64.x.x.x (next hop address)

instead of just ip route 0.0.0.0 0.0.0.0 Ethernet0
