To find out your ip-address, start/run "cmd", then when the black window pops out type "ipconfig". The second value should be ip-address.

Port can be anyhting as long as all players are using the same port. Also, as ports under 1024 are reserved for special use, it's customary to pick a (considerable) higher one, like 20000.

And for safety: Think of your ip-address as your home-address. If no-one knows it, no-one can ever come throw stones at your windows. Also, if no-one knows it you will never recieve mail or have anyone visit.

For you to ever get anything from the web you have to send in your address. For example your ip-address will be visible to the webmasters of every web-page you ever view. When you loaded this page your computer sent your ip-address and a page request to shrapnelgames.com (69.56.133.50), that then processed the request and sent a reply to your address.

So, trying to hide your ip-address is rather futile...
