    Customer A Network:

    Customer B Network Hosts to reach: &

    Customer B requires us to double-nat as a single IP i.e. to reach the 10. hosts. Somewhere in between the routing, another network is being used thus Customer B is requiring us to use

    Question is, I believe I'm close on the config:

    ip nat inside source static route-map xx-map
    ip nat outside source static route-map xx-map
    route-map xx-map permit 10
    match ip address alt-acl

    ip access-list extended alt-acl
    permit ip
    permit ip

    Need some guidance here, because it's not working :(

    Have you considered Overloading? That will allow one-to-many address translation. Of course, depending on the type of applications used on your network, some additional ports will need to be opened or you may have to re-think the one to many scheme.

    But it sounds like that's what your reaching for.
