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.

I have handled one issue, license appxk9 is necessary at ISR4k for PPPoE, ipbasek9 is not enough.
---------------------------------------
Restriction - appxk9 must be active on the ISR4000 router. Without this license, the route will get installed towards the client at the end of PPP negotiation, but Layer 3 connectivity between the client and the server will not be established.
---------------------------------------
Please kindly try "license boot level appxk9" .
