Configure Cisco PIX 501 to accept VPN traffic thru a PPPoe setup

Posted on 2009-02-11

I currently setup a Cisco PIX 501 router to be used behind a DSL moden set in Network Bridge Mode.  It has been setup to accept PPPoe but now I would like to setup the Cisco to accept connections from the outside via a VPN.

How can I configure the PIX to accept this traffic?

Here is the current config:

PPPoE Assigned IP addr: on Interface: outside
   Remote IP addr:
pixfirewall(config)# show config

    Simplest way is to just run the PDM VPN Wizard and walk through all the steps.
    When it comes to identifying an ip address pool for the vpn clients, use a different sbunet than your internal 192.168.1.x

    I can't access the PDM.  I would have to update the version and I don't have an account to download the upgrade.

    Anyway around that or do you have a command line way?

    of course there is command line ways.

    Not following.  How does the client establish the VPN tunnel to the pix from the outside.  Based off my configuration, what would be the host address for the outside interface of the PIX?

    >ip address outside pppoe
    Given that your IP address is dynamic, you would have to find it using "sho interface"
