Running NAT on 7200 DSL aggregator

I have a 7204 with an ATM circuit carrying PVCs for our DSL subscribers. I have authentication working and the connectivity is good. However, I want to NAT the subcriber traffic coming into the router on the ATM circuit to a global IP on the Ethernet inferface. For some reason it will not translate traffic coming in over the subinterfaces of the ATM circuit. Help would be appreciated. My config looks something like this:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

aaa new-model

aaa authentication login default local

aaa authentication ppp default group radius

aaa accounting network default start-stop group radius

vpdn-group 1

accept-dialin

protocol pppoe

virtual-template 1

interface FastEthernet1/0

ip address 192.168.1.17 255.255.255.192

ip nat outside

interface ATM2/0

no ip address

atm scrambling cell-payload

no atm auto-configuration

no atm ilmi-keepalive

no atm address-registration

no atm ilmi-enable

interface ATM2/0.32 point-to-point

ip unnumbered Loopback0

ip nat inside

class-int test

atm route-bridged ip

pvc 1/32

encapsulation aal5snap

protocol ppp Virtual-Template1

protocol pppoe

interface Virtual-Template1

ip unnumbered Loopback0

peer default ip address pool dsl

ppp authentication pap chap

ip local pool dsl 10.1.1.5 10.1.1.6

ip nat pool test 192.168.1.5 192.168.1.6 netmask 255.255.255.192

ip nat inside source list 1 pool test

ip classless

ip route 0.0.0.0 0.0.0.0 192.168.1.1

access-list 1 permit 10.1.1.0 0.0.0.255

radius-server host 10.1.1.3 auth-port 1645 acct-port 1646

radius-server retransmit 3

I have seen small issues with access-list 1. Change the access-list to access-list 11 and the NAT should work.
