I am attaching a sample config and do the needed changes in IP addressing according to your network and hopefully this should work without any issues.

Try to follow the link from Amit, check the DHCP configuration section and follow the template. It tells how to configure DHCP + ATM connection in the router. It is helpful.
Hope this helps.

Hi,
The username and password which appears on the sample config is your login credentials and which is not related to the CHAP or PAP.
Try using the above said sample configs and ask your ISP for the Default gareway address. You can use the below DHCP as a sample for configuring the dhcp server.
ip dhcp pool YOURPOOL
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server XXX.XXX.XXX.XXX XXX.XXX.XXX.XXX
Also, is there any reason for using the routing protocal (rip) ????
Thanks
Rajesh

I found there is no IP at Etherent interface, please assign your private address.
Please try below commands that extract from the sample and fine tuned for your setting.
ip routing
bridge irb
interface Ethernet0
ip address x.x.x.x y.y.y.y
no ip directed-broadcast
ip nat inside
no bridge-group 1
interface ATM0
no ip address
no ip directed-broadcast
no atm ilmi-keepalive
bundle-enable
no pvc 0/32
no encapsulation aal5snap
interface ATM0.1 point-to-point
no ip directed-broadcast
pvc 0/32
encapsulation aal5snap
bridge-group 1
interface BVI1
ip address dhcp client-id Ethernet0 <-- This help to get the IP address from ISP via DHCP
no ip directed-broadcast
ip nat outside
ip nat inside source list 1 interface BVI1 overload
ip classless
ip route 0.0.0.0 0.0.0.0 BVI1
access-list 1 permit x.x.x.x z.z.z.z <-- your Ethernet segment address
bridge 1 protocol ieee
bridge 1 route ip
Please let us know the result and the error message if it fails.
Hope this helps.

Hi,
You can also try binding the dialer interface to the ATM under the ATM interface config
pppoe-client dial-pool-number 0
Hope this helps
