If you don't need the "internal" machines to have these new public addresses directly, but can settle for NAT'ing, then it's relatively easy:
interface ATM0
ip address 222.222.222.2 255.255.255.252
ip nat outside
no ip unreachables
!
interface Ethernet0
ip address 10.10.10.1 255.255.255.0
ip nat inside
!
! The following route should be you public NAT network
ip route 82.82.82.0 255.255.255.0 Null0
ip nat inside source static 10.10.10.10 82.82.82.10
ip nat inside source static 10.10.10.11 82.82.82.11
!
This is given that the ISP routes the 82... network to your interface address on the ATM-link..
But if you want the "internal" machines to have the public addresses configured, you could put a secondary address on your internal LAN-if:
NOTE: THIS IS NOT A RECOMMENDED SOLUTION!!
interface ATM0
ip address 222.222.222.2 255.255.255.252
ip nat outside
no ip unreachables
!
interface Ethernet0
ip address 10.10.10.1 255.255.255.0
ip address 82.82.82.1 255.255.255.0 secondary
ip nat inside
!
Now you can have both internal addresses and public addresses on the LAN.. but... THIS IS NOT A RECOMMENDED SOLUTION!!!
