this...I just posted again because you should knowLAN = Local Area Network
If ya want people who are not connected to your LAN to get in, you need to use something inbetween like Hamachi.
What about internet security programs? Will I have to okay it through them? I feel like allowing people to directly connect to your comp via. IP+port would be a "compromise". In other words, it's not like I'm getting some online proxy to host my server, I am letting people connect to my comp.
