Port forwarding won't be an issue, unless you are moving traffic across the WAN..... If you are streaming files from a DNS-323 to a 360 in the same LAN, port forwarding won't be an issue. Port forwarding (I am fairly certain... brain a bit fuzzy now) is used in situations where you have NAT (Network Address Translation) working... or.... 1 IP address from the ISP, and many computers behind a router. Good find though.
