I have a Cisco 2600 router. I have it pulling DHCP from the ISP. Wanside is performing address pull. The ISP can see my router from the outside. However, I can get no internet connection from my internal LAN. This is my running config:

no aaa new-model
ip subnet-zero
ip cef
ip name-server 204.yyy.yyy.yyy
ip name-server 216.yyy.yyy.yyy
no ip dhcp-client broadcast-flag
interface Ethernet0/0
 description line Real World Interface
 ip address dhcp client-id Ethernet0/0 hostname Wewahitchka
 ip nat outside
interface Ethernet0/1
 description LAN INTERFACE
 ip address
router rip
ip http server
ip classless
ip route 12.yyy.yyy.1

You need to setup NAT in order for workstations to be able to connect.
  Do this:
access-list 100 permit ip any
ip nat inside source list 100 interface e0/0 overload

If 12.yyy.yyy.1 is your ISP's gateway, then there's no point in having RIP configured with it.
  Also do this:
router rip
  no network

I need to apply this access-list to my Lan or Wan inteface?

Nope, just run those 2 lines at the top of my post.  The ACL is just telling the router what subnets to NAT to the outside.  
Oops, just noticed you don't have 'ip nat inside' assigned to your interface...
  Run this:
int e0/1
ip nat inside

*Now* you should be good to go.  Sorry, I saw 'ip nat outside' on the external interface & didn't closely check your LAN interface.  Need my morning caffein!
