Multiple clients behind one firewall

I am have a problem, which I am positive is not unique.

I live in a place with more than just me. Both me and my roomie use second life. While doing research on the best way to configure firewalls with SL I found this:

18. Will my firewall prevent me from accessing Second Life?

Second Life needs to connect to ports 443/TCP, 12035/UDP, 12036/UDP, and 13000-13050/UDP. You should configure your firewall to allow outbound traffic on those ports, and related inbound traffic.

Now, the first part of this is no problem. Port 443TCP the firewall can handle NATing fine.

However the rest of it is a disaster. It lists 52 UDP ports which it says to forward to the client. The problem is, I have more than one potential clients at any give time! It also doesn't tell me what ports to expect the 'related inbound trafic' on the UDP. The assumption is 'the same', but it's not explicitly defined.

So how do people handle this situation? I thought of port triggering, but that has the same issue as forwarding, only one client at a time can own the trigger.

With multiple clients, you shouldn't port forward at all.

Most consumer routers can be left in their default configuration. This way, they open any necessary ports as your computer requests them, while blocking unsolicited outside traffic. I didn't have to change a single setting on my router to use multiple SL clients at the same time.

If your router does give you problems, though, you should check out this page instead:
