NAT OVER GRE

Hi Experts,
 
I have question regarding NAT OVER GRE:
 
- Router with interface FA0 (Also have gre tunnel), natting working fine,
but when traffic going over GRE, it doesn't nat.
 
- ip nat inside source route-map Tunnel1_Tunnel2 pool PUBLIC overload
   - route-map Tunnel1_Tunnel2
     match ip address From_Source
     match interface tunnel1 tunnel2
 
ip access-list standard From_Source
permit 192.168.23.0 0.0.0.255
 
ip nat pool PUBLIC x.x.x.x x.x.x.x prefix-length 24
 
Router#sh ip route 172.16.24.0
Known via "eigrp 1", Last update from Tunnel1
 
When you ping 172.16.24.0 sourced from network 192.168.23.0 (vlan), it wont
ping and obviously won't nat., if you ping without source it will ping but
take the public ip from interface as the inside public and not from PUBLIC
pool.
 
ip nat inside source route-map PUBLIC_INTERFACE interface FastEthernet0
overload
 
- route-map PUBLIC_INTERFACE
  match ip address 150
  match interface fastethernet0
 
Any ideas?
