There is a difference[1] between using the generic TCP proxy and the filter
even when you configure the proxy to use the original IP address.  Namely,
the application proxy changes the source port.  If the Veritas software
rejects the packets if they have a different source port then what it
expects, then what they say would be true.

[1] From my tests on 5.2.1.xx.  I didn't see, but perhaps missed, an option
to change that behavior for the TCP proxy.
