PPPoE on Cisco routers (ip address asigment dynamic from server)

after several investigations have working configuration.
main requirement is to assign ip address for pppoe session for client (R3) from server (R4)

here goes config:
vpdn enable
!
!
!
!
interface Ethernet0/0
no ip address
full-duplex
pppoe enable
pppoe-client
dial-pool-number 1
!
!
interface Dialer1
ip address negotiated
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer persistent
!

vpdn enable
!
vpdn-group 1
accept-dialin
protocol pppoe
virtual-template 2
!
!
interface Loopback100
ip address 150.1.34.1 255.255.255.255
!
!
interface Virtual-Template2
ip unnumbered Loopback100
peer default ip address pool test_01
!
ip local pool test_01 150.1.34.2

main tips:
1. on Client (R3) ip address negotiated in dialer intrface must be used
2. on Server (R4) under virtual-template 2 must use some ip unnumbered interface. Otherwise interface comes up but no ip address from local pool is asigned. Configuration was working in WB presentation, but in real lab not!!!

some outputs:

R3#sho ip ro

150.1.0.0/32 is subnetted, 2 subnets
C 150.1.34.1 is directly connected, Dialer1
C 150.1.34.2 is directly connected, Dialer1
