I am attempting to configure my 2621 for the first time with my ADSL WIC in place and am just wondering if anyone has any sample configs on how to do this.  I have attempted before but unsuccessful and have since reloaded IOS and am loading from the ground up.  Thank you in advance.

Several different ways, depending on how what your provider requires:

Try the following for static addresses from the provider.   If using PPPoE see further down...

------STATIC ISP Config--------
! Static with ADSL
bridge irb

interface ATM0/0
 no ip address
 no atm ilmi-keepalive
 pvc 0/35
  encapsulation aal5snap
 dsl operating-mode auto
 bridge-group 1

! Must use BVI as 99% of all providers offer bridged service.
int bvi 1
   ip addr <static ISP address> <mask>

!PPPoE with ADSL....

vpdn enable
vpdn-group 1
  protocol pppoe

interface ATM0/0
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto
interface ATM0/0.1 point-to-point
 pvc 0/35
  pppoe-client dial-pool-number 1

interface Dialer1
 ip address negotiated
 ip nat outside
 encapsulation ppp
 dialer pool 1
 ppp authentication pap callin
 ppp pap sent-username <username> password <password>

int e0/0
   ip addr <private inside IP> <mask>
   ip nat inside

ip nat inside source list NAT-INET interface Dialer1 overload
ip access-list extended NAT-INET
 permit ip <private inside net> <private inside mask> any

So if I set it up for static as stated above, I need to setup the BVI 1 to be the external address and I will set up my FA 0/0 to be the internal address of my network.  Then I need to setup my routs between the two networks?  Just making sure I have it all straight in my mind.
