[c-nsp] Best practice in configuring internet access services.

Have you tried using named access-lists ?
interface f3/3.333
ip access-group f-3-333-acl-in

ip extended access-list f-3-333-acl-in
permit ip ....
permit ip...
end

PPPoE is also widely used on cable (HFC) networks, which are Ethernet
in nature.
But I suggest you the same many already have: get rid of NAT, provide
your customers a clean access pipe with a non-RFC1918 IP so they can
happily use SIP, H.323 and other multimedia protocols, and you can use
scalable solutions to deploy your service.
