Hello

Make sure that your Cisco router (PPPoE server) has a default route towards the Internet and that your PPPoE clients receive a default route (over IPCP or static configuration). Then configure NAT:

access-list 10 permit 192.168.44.0 0.0.0.127

interface Virtual-Template1
 ip nat inside

interface FastEthernet0/1
 ip nat outside

ip nat inside source list 10 interface FastEthernet0/1 overload

I think you're also missing a vpdn enable command from your Cisco router.

Best regards,
