To Port Forward or Not To Port Forward - That is the question

System: DP MDD G4, OS 10.4.9

Inet connection: DSL with static i.p.,Broadcom Gateway to Linksys
WRT54G Wireless Router using DHCP, 1 computer connected via enet, 3
connected wirelessly, basic home use only

Wireless security is very basic: Unique router name and pw, SSID
disabled, and connections allowed by MAC addresses only, Linksys
firewall is enabled with all the other features set to their defaults,
Mac OS firewall is disabled

I recently purchased a Logitec QuickCam Pro 5000 webcam that works just
fine with iChat right out of the box. Learning how to use it I found
some Apple docs and other docs that discuss the various ports that
Apple uses when communicating to the inet whether by text, audio,
video, etc. The Port Forwarding setup window in the Linksys is blank so
I assume it uses whatever port is available for whatever it needs to
do. Is there any distinct advantage (speed-wise or security-wise) to
using the specific port ranges suggested or should I just leave well
enough alone because it all works just fine with no problems? Thanks.
