dhcp issue

Hi All,

got stuck in a small issue of DHCP.please help

*Scenario* :-

R1 & R3 are connected back2back via serial link running PPP.
R1 is requesting ip via IPCP, R3 is a dhcp-proxy pointing to Dhcp server
pointing to R2.

R3 & R2 are also connected back2back via serial link .

*Issue* :-

R3 is forwarding dhcp request from R1 to R2. That is as expected.
R2 is receving the requet & allocating 1 Ip address (I can see in "show ip
dhcp binding").That is as expected.
But on R1 status is still "Internet address will be negotiated using IPCP"
....??
Also on R1 not able to see any dhcp debug logs.

*Configs*:-

R2#sh running-config | sec dhcp
no ip dhcp use vrf connected
ip dhcp pool R1_ip
   network 180.1.31.0 255.255.255.0

R2#sh ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
                    Hardware address/
                    User name
180.1.31.1 0063.6973.636f.2d31. Jan 04 2010 12:12 PM
Automatic
                    3830.2e31.2e33.312e.
                    332d.5365.7269.616c.
                    312f.32

===================================
R3#sh running-config int se1/2
Building configuration...
Current configuration : 200 bytes

 ip address 180.1.31.3 255.255.255.0
 ip accounting output-packets
 ip flow ingress
 ip flow egress
 encapsulation ppp
 peer default ip address dhcp
 serial restart-delay 0
end

R3#sh running-config | sec dhcp
ip address-pool dhcp-proxy-client
ip dhcp-server 150.1.2.2

===================
R1#sh run int se0/1
Building configuration...
Current configuration : 69 bytes
!
interface Serial0/1
 ip address negotiated
 encapsulation ppp
end

R1#sh int serial 0/1 | i add
  Internet address will be negotiated using IPCP
