Can't get through ASA 5505

Hi, I'm sorry to ask, but have been battling with this for days now.  I've been tasked with setting up an ASA 5505 on our ADSL modem & am very lost.  I've put the PPPoE details into the ASA 5505 to authenticate with our ISP, but can't get out through it.  I've looked at guides, videos, compared configs, but can't see where I'm going wrong.  Can someone help please, I know it's supposed to be secure, but not quite this secure.  I'm going crazy!

This is the current config...

Re: Can't get through ASA 5505


Your config looks fine to me. There are a couple of things that you'll need to do with your policy map. First of all, from the ASA, can you ping successfully? If not, do a "vpdn session pppoe state" to see if your session is up. If you aren't up, the something is going on between the ASA and the provider. You could try changing the authentication to pap, because believe it or not there are still some providers out there that still use it.

Otherwise, if you CAN ping successfully, then add the following:

policy-map global_policy

class inspection_default

inspect http

inspect icmp

See if that will get you out.

** Edit **

Make sure that you have a DNS server assigned to your clients as well:

dhcpd dns

Re: Can't get through ASA 5505

Hi John,

Please try this.

show route

and look for an output as shown below.

Gateway of last resort is to network

In my case, my default-gateway happen to be at

If you still have the issue, then.

config just like I have on my ASA shown below and I do not have an SVI (vlan) interface for outside but rather, I go directly on the interface itself.

interface Ethernet0

nameif outside

security-level 0

pppoe client vpdn group bellnet

ip address pppoe setroute

vpdn group bellnet request dialout pppoe

vpdn group bellnet localname b1nkbaxx

vpdn group bellnet ppp authentication pap

vpdn username b1nkbaxx password ********* store-local

dhcpd dns

Let me know, if this helps.
