Here's a puzzler for you:

"Their" 192.168.10.0/24 Network
        |
"Their" Default gateway
        |
"Their" VPN 3030 Concentrator running PAT w/ external interface 2.2.2.2
(Reference Point A)
        |
Another default gateway leading to...
        |
The Internet
        |
"My" gateway router
        |
"My" VPN box
        |
"My" internal router possibly running NAT (Reference Point B)
        |
"My" 172.16.0.0/14 network


The VPN boxes are up and running and have a tunnel established.  Okay, so at
Ref. Point A, we're running PAT on the VPN box to hide the 192.168.10/24
network.  Fine and dandy.  For some reason, management has said that all
source addresses coming into "my" network must be 172-based addresses rather
than the 2.2.2.2 address.  So they want to know if at Ref. Point B if I can
run another NAT session which translates the 2.2.2.2:Port addresses into
172.16.0.0/14 addresses.  I would think this wouldn't be possible, because I
know of no NAT command which allows you to specify the outside local
addresses as being PATted addresses.  Is there such a command?  Thanks.

P.S. Someday, "their" 192.168.10/24 network will be renumbered.  This is
just an interim configuration.
