    I am looking for a little guidance on coming up with a configuration
    for a very complicated situation. What I'm looking to do is to run a
    PPPoE ADSL connection on a Cisco 1801. This 1801 will then need to do
    an IPSec tunnel back to a Juniper ERX.

    Also, I will need to do several Static NATs with one of the subnets
    that will be tunneled. For example, the ethernet subnet of the Cisco
    will be I will then route via the
    IPSec tunnel and will need to create specific Static NAT's throughout
    the subnet, such as will equal

    The real problem I am trying to wrap my head around is doing the Dial
    Backup and then doing a NAT Overload on the Dialer interface in
    conjunction to the vpdn pppoe dialer and the IPSec tunnel with Static
    NAT configs.

    Any thoughts or suggestions?
