I would like to combine private and public addressing to PPPoE clients from a Cisco BRAS.
Do you think is possible to do it using the same virtual template?
If I define ip nat inside in the PPPoE enabled interface and an access-list that will match only the addresses want, would this impact clients with public IP address?
I am sure that using different templates would work, but I would like to try using the same VLAN and not to separate some clients in a different VLAN.

From NAT perspective you wont have problems, as long as your are using correct access-lists. So for example, permit only private ip range in acl and use this acl in ip nat inside source list (private range acl) pool blabla overload. NAT will be created only for those packets that match acl. Public ip addresses will use normal routing.
