PPPoE Question tman 04-18-08

I had the configuration on my ASA5505 just the way I wanted it. For
testing I had it setup with private address on the inside and a
private address on the outside. It forwarded traffic observing the
rules I had configured.

It will be deployed using a DSL line on the outside. I changed the
outside interface to use PPPoE, took it home and connected it to my
ISP via DSL to test it. It made the connection successfully and got
an ip address. The DHCP server on the ASA served up a proper stack to
internal hosts. I could not access the Internet through the ASA. I
tried the packet tracer and it reported no route.

I checked my routing table and this is what it was:

C        127.0.0.0 255.255.0.0 is directly connected, _internal_loopback
C        192.168.1.0 255.255.255.0 is directly connected, inside

Is this normal for PPPoE? Any reason that changing the outside
interface from static to PPPoE should make the ASA stop forwarding
traffic?

Any suggestions will be appreciated.

Thanks.
