[c-nsp] NAT-ON-A-STICK for VRF Traffic

[Andy Saykao]

I want to set up a NAT-PE Internet Gateway and NAT vrf traffic using
NAT-ON-A-STICK. Is this possible? 
 
Easy enough to do when it's IP traffic using policy-based routing as per
this article:
 
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a
0080094430.shtml
 
Just wondering how you would apply the article in relation to when the
traffic is MPLS/VRF based.
 
I tried this config, but could not get it to work.
 
NAT-PE Router:
 
interface Loopback98
 description Used for NAT-ON-A-STICK
 ip address 172.16.76.25 255.255.255.248
 ip nat outside
!
interface GigabitEthernet0/0.11
 description Core/MPLS Network
 encapsulation dot1Q 11
 ip address 203.10.110.X 255.255.255.224
 ip nat inside
 ip virtual-reassembly
 ip policy route-map NAT-LOOP
 mpls ip
!
! Set default to next hop on P router in the global routing table
ip route vrf NSTEST 0.0.0.0 0.0.0.0 GigabitEthernet0/0.11 203.10.110.Y
global
!
ip nat pool NSTEST-NAT-POOL 210.15.230.65 210.15.230.65 netmask
255.255.255.252
ip nat inside source list NSTEST-NAT-ACL pool NSTEST-NAT-POOL vrf NSTEST
overload
!
ip access-list standard NSTEST-NAT-ACL
 permit 192.168.0.0 0.0.255.255
!
route-map NAT-LOOP permit 10
 match mpls-label
 set ip next-hop 172.16.76.26

P Router:
 
! Route public ip's to loopback98 on NAT-PE router
ip route 210.15.230.64 255.255.255.252 Loopback98 172.16.76.25
 
My logic is flawed somewhere ;)
 
Thanks.
