Cisco 5505 PPPoE Setup

jill.kane — Mon, 11 Mar 2019 19:53:02 GMT

Please help!

I am trying to configure my Cisco ASA 5505 to use with a Netopia 3347 from AT&T. I have set the Netopia modem into bridge ethernet mode properly, and I have the correct username/password in order to gain access to the Internet but for some reason the PPPoE configuration is not working properly. I have verified with AT&T that it is authenticating and it is receiving the correct ip address but I am unable to access the internet. Here is my current configuration:

Hey,

In your config you have :-

interface Ethernet0/5
switchport access vlan 12

Should this not be

interface Ethernet0/5
switchport access vlan 1

I have gone completely back to the factory configurations so that I can get this PPPoE enabled. I am still unable to get internet access through my firewall but it is correctly authenticating. Please help!

Here are my current configs now:

Hi there,

Can you enter the following command on your unit :-

packet-tracer input inside tcp 192.168.1.10 8888 208.208.208.208 80

And if you can't interpret the output of packet tracer, post the output here for us to see.

Regards

Paul.

Hi,

You wont have internet access, because the ASA does not have a route to get there... Are you getting an IP address from the pppoe server? what happens if you do a show ip address outside pppoe?

I think you are also missing the command on the interface setroute... it would be like this

ip address pppoe setroute

With that command he will ask the PPPoE server the default gateway in order to access the internet. I am going to be here for a couple of more hours.. Let me know if you need help.

Cheers

Mike

I agree with Maykol,

Your ASA has no route to any network other than the connected subnets as the output of Packet Tracer suggests.

Enter the command :-

ip address pppoe setroute

Under your VLAN 2 interface and you should be good to go.

A Technote describing your situation resides here:-

Hope this helps.
