You can connect to a server with direct connect, (or do you mean something else?) and you don't need hamachi, you only need it for servers that are hamachi and you need to join the network on hamachi for the server if the server is hamachi.
Link to hamachi btw https://secure.logme...i/download.aspx if you don't have it already
if you are looking for a server you can search the server section on the forums
