Routing 2 different streams from the same IP address

Archived from groups: comp.security.firewalls (More info?)

Hi All,

Forgive my ignorance, but I am not really the network admin I'm just
trying to get information to understand our problem better.

We have a box that runs 2 different applications that both send
interfaced data. We are in a situation now that requires us to route
the 2 streams over the the same firewall (Cisco PIX) to 2 different IP
addresses and ports. The issue we are having is that the streams come
from the same IP and we can't use port translation as each time the
application opens a conenction it grabs any available port (we are
unable to set a static port to send from on the applications). So we
haven't figured out how to seperate the streams since we can't define
the port they are originating from.

Basically IP n.n.n.140 sends 2 streams of data over 2 different ports
that are dynamically chosen from the normal range. Stream A needs to go
to destination n.n.n.8 port 850, and stream B needs to go to
destination n.n.n.14 port 6343.

Any ideas to set us on the correct path would be appreciated.

Thanks,
Cory
