How can I enter a server?

[Lukitas]

Hi guys, I'm Spanish and my English is not well... :S
I've just download the last version of Glest. I try enter to a server, but I can't do it. If I put a New Server he can't connect me, and I can't select another option!
Please, give me a number of a server to connect and I will try put it to connect...
Help me please.

Thanks everybody ;)

Well, For internet (if u are not the host), you have to know the host's IP Adress, (if u are the  host) u need to port forward, that is a bit harder, and im sure someone else may tell u instead of me having to. and for LAN, you don't need and port forwarding, just get eachother's IP ADRESS
