For this config, u don't need to configure a dhcp pool.
A simple local pool is enough to supply ip addresses for dial-in hosts.
If trying to configure "peer default ip address", u have 3 options:
A.B.C.D Default IP address for remote end of this interface
dhcp Use DHCP proxy client mechanism to allocate a peer IP address
pool Use IP pool mechanism to allocate a peer IP address
So, google "DHCP Proxy client" and u will understand ur fault.
!!!!
IPCP is the way PPP (pure) hands IP addresses attribution. Very different from DHCP; This is why local pool is the better way to achieve what u want.... I know that Windows RRAS can DHCP dial-in hosts.
About DHCP...., if R5 were connected to another router, this one configured with a DHCP pool, perhaps, u will achieve your goal.

Objet : Correction to DHCP Ip Address Negotiated.....
Sorry for the copy-paste mistake on R5, int dialer 1. I just
double-checked & repasted the debug output. This the correct config:
