I was watching this Video which talked about using port-forwarding to optimize your LAN for skype calls. According to the video, as explained in the first couple of minutes in the video, the reason you would need optimization is because if the person your call has a firewall setup, your connection has to go-through a third-party computer to connect to them. I believe I stated this correct (maybe not).
None the less, my question is this: do both parties on the call need to enable port forwarding to optimize skype, or just one party (person)?

Generally speaking only the person that is RECEIVING a connection should need a port forward. But it's really best if you port forward on both ends.
A good place to start is the portforward.com guides for Skype. You can get to them here: portforward.com
They should have a writeup specifically for your router and Skype. If not, just let them know and they'll add it.
BTW, UPNP is an option as well, but lots of computers have it disabled and lots of routers do not support it. If you want to be certain then forward the ports.
