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 !
