Overload without static!

Hello there,

I have the following scenario"

                          110.110.100.0/24
R1(S0)-----------FRAME CLOUD--------------(S0)R3--------
  | \
E0(VLAN1) \
                                        (S0)R2
I have to configure NAT on R1 so that all hosts on VLAN1(leaving VLAN1) toward FRAME CLOUD will be given an IP address in the range of 110.110.20.8 through 110.110.20.10 with a 29 bit subent mask. ALL HOSTS must be supported by this nat.
The rest of the network must see VLAN1 route and the 110.110.20.0/24
network. Here is my config:
R1
interface E0
ip address 13.13.13.1/24
ip nat inside
!
int serial 0
ip add 110.110.100.1/24
IP nat outside
!
ip nat inside source list 10 pool NAT overload
ip nat pool NAT 110.110.20.8 110.110.20.10 netmask 255.255.255.248
!
access-list 10 permit VLAN1
end
If I create a staitc entry an redistribute it into the IGP, everything works. Same thing if I create a loopback interface and redistribute it into the IGP, works.
My question to you, how can I meet all the requirements if static, or to create a new interface is not allowed?
Thank you
Nathasha
