Cisco WAN :: Minimize IP Usage On 2911 And Keep NAT

I have a problem I am running into... I replaced a 2621 with a 2911. The 2911 has three interfaces and I need to use all of them... Description:
 
gige0/0 dhcp static IP from ISP, public IP, they assign me 4 more usable public IPs gige0/1 broken into four VLANS, 108, 109, 120, 127, ip nat on 109 for them to get to the internet, and a static translation on 127 for the phone system to get to the internet gige0/2 assigned another public IP. A tenent has a linksys router on this interface, they want a public IP.
 
The problem is that this setup worked, but when we moved to the 2911, some nat translations are failing, and we would like to figure out how to minimize the number of public IPs we use (right now it is three + the static assigned dhcp). The nat that is not working is the nats to the 2001-3001 range. I am not sure why it is failing, but the router seems to indicate it thinks some of these overlap. This router is also doing a vpn to an asa... that seems to be working fine.
