I dont have a router in front of me to test but I would guess if the pool is
on a remote server you will have to give the router a hint on what DHCP
server to use. Dont want it broadcasting out all interfaces. I would
try adding "ip dhcp-server <R5 Address>"
There is also an example of this type of config at:
