PPPoE Server is not routing properly.

[netopia]

I have recently configured an ISR 4321 to act as a PPPoE server.  I have moved the configuration wholesale over from my old 1941 router.  Clients now are able to authenticate and get a PPPoE address, but are unable to reach the gateway, or indeed, anywhere else.

It strikes me there is probably something missing, but I can't figure it out.

Here's the configuration I have:

bba-group pppoe global
virtual-template 1
!
interface Loopback1
ip address 10.64.249.1 255.255.255.0
!
interface GigabitEthernet0/0/0.2009
description pppoe interface
encapsulation dot1Q 2009
pppoe enable group global
!
interface Virtual-Template1
description pppoe interface
mtu 1492
ip unnumbered Loopback1
peer default ip address pool PPPnet
keepalive 300
ppp authentication pap chap
ppp ipcp dns 10.64.1.2
!
ip local pool PPPnet 10.64.249.101 10.64.249.199
!

From ppoe client does it have a default route?

sh ip route 

If not either apply a static default route or enable an ipcp default to the client dallier interface

conf t
ip route 0.0.0.0 0.0.0.0 dialer x

or

int dialer x
ppp ipcp route default   <--restart interface after applying

I've got a default route on my client (it's not a cisco product), so it's not the route for the client.
