Does port 8333 have to be opened?

[ksd5]

I was running the "Generate Coins" feature of Bitcoin. I have not opened up port 8333. It says it has 8 connections, and the number of blocks just keeps going up and up. (It's over 50,000). It hasn't generated any coins yet.

Is it working properly, or do I have to open up port 8333?

You do not have to open the port. It really just helps you get better connected to the network. If things are working, you're all good.

I'd like to use this feature, but I'm not sure what to set in my Linksys WRT54G router. I think it's the Applications and Gaming section I want, and the following is what I entered. But I don't know about the "Port In" and "Dest. Port" difference. Should they both be 8333 like I have them here?
 
Name: Bitcoin
Port In: 8333
Dest. IP Address: 192.168.1.3
Dest. Port: 8333
Protocol: tcp

yeah, usually you just forward the inbound port to the same destination port.
that only differs if you run a service locally with a certain port, but you want people to connect to the service via another port.
this scenario wont really apply to the normal computer user.

That should be exactly what you need. Do you have more than 8 connections to your client now?

Thanks. I think I got up to 15 connections a couple of days ago when I first installed bitcoin.
