I am trying to configure my static ip address with CenturyLink. 

here is the config that I am using:

interface ATM0/0/0.1 point-to-point
ip address
ip nat outside
ip virtual-reassembly in
ip traffic-export apply bandwidth_hog size 10000000
atm route-bridged ip
pvc 8/35
encapsulation aal5snap

ip route

ip nat pool NAT-POOL netmask

ip nat inside source list NAT pool NAT-POOL

You need an access list to allow internal address (lan)

access-list 100 permit ip x.x.x.x x.x.x.128 where x.x.x.x is your internal segment.

also, in your NAT statement, you need to include the access list number 

ip nat inside source list 100 pool NAT-POOL

Can you post "sh run"


I have the access list

and the reason why it says ip address dhcp at the moment is because if I don't have that and I am using my static ip address then the internet will not work

Hello everyone,


I have figured out the issue, it turns out the address was tied to my mom's CenturyLink business DSL circuit and not to my residential DSL circuit, I have a phone call scheduled for tomorrow to call CL and have them change my address to be on my circuit and not my mom's circuit.
