that's not possible because the internal addresses are presumably private
and non-routable so it sounds like you need to write a masq helper module
for whatever this application is that handles it when the external software
tries to connect back to the internal software, it'll connect to the
masquerading host which then automatically port forwards the connection to
the right internal host. the autofw module will probably do what you want but
it's been said that it's not stable and can crash the kernel if overused.
