Client Access to VPN'd system

Using CA v3r2 to access several systems.  I am using CA v3r2 vs. CAE because
of lowest common denominator factors.

Our shop also uses ViewNow, which is able to connect to remote AS/400s thru
a VPN setup.  In ViewNow, I set up a session with an internal IP address
like 192.168.x.xx and port 8045.

CA v3r2, when setting up a connection, it only asks for the IP address.
Obviously, it's not going to find a 400 at that address.  Strangely enough,
the client (Personal Communications WorkStation Program) gives the
opportunity to specify a port (and I see this in the session.WS file as
well) via the Communication menu, then Configure option.  On a whim, I
change the port number from the default 23 to 8045.  But this doesn't work;
no connect.

Is this beyond the capabilities of CA v3r2?  Or is there a tweak I missed?
I trust CAE can do this?
