I would be very surprised if this were true. I forward ports > 1024 all
the time. You can confirm what is happening by sniffing on the NAT box with
tcpdump.
tcpdump -i any tcp port 6346
That should show both interfaces, and all tcp traffic on port 6346. You
should see the traffic coming in, and then being forwarded on.
