    Customer A Network: 172.16.1.35/32

    Customer B Network Hosts to reach: 10.1.80.50 & 10.1.40.50

    Customer B requires us to double-nat as a single IP i.e. 192.168.19.10 to reach the 10. hosts. Somewhere in between the routing, another 172.16.1.0 network is being used thus Customer B is requiring us to use 192.168.19.10.

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

    ip nat inside source static 172.16.1.35 192.168.19.10 route-map xx-map
    ip nat outside source static 172.16.1.35 10.1.80.50 route-map xx-map
    !
    route-map xx-map permit 10
    match ip address alt-acl

    ip access-list extended alt-acl
    permit ip 192.168.19.10 10.1.80.50
    permit ip 192.168.19.10 10.1.40.50

    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.
