Help with multiple player "server".

Ok, First off, I'm assuming this is right place to post this, Right? Cause This my first topic...
Second off, I CANNOT make a multi-player server. I tried Non-dedicated AND Dedicated... It only puts it on LAN...(I had someone check if it was LAN or not)and I also... Sorry if this is stupid or something. But, I also want to cheat in my server. And only ME cheating in it. I know it won't be very fun for the other but I REALLY want to do this. Plus, I want to make my own game/server and it to be on multiple player anyways.
1) I did some ports that is told. You can say all the ports that might be needed for it to work just in case I missed any.
Even then I turn off my fire wall completely and it STILL did not work.
2) I went to Multiple player: and click "Create Game" or whatever its called ... still it put it on LAN.
3) I did dedicated and I allowed cheats and all... The cheats worked. But, I have to get used to it. but, When I do dedicated it did LAN as well.
[V-ADD-V]
4) I checked myself if it was on LAN it not. And yes its not on multi-player. Someone said before saying it might just not be showing on multi-player list... well it still seems it not on multi-player at all... Cause, I'd play it for quite some time and no one joins. So, I doubt its on multi-player.
[^-ADDED-^]
I'll post more later. I'll keep trying. but, Can someone help me with this. Also, I know my spelling and grammar ain't that great and also I know it won't be fair with only me cheating but I really want to try it anyways.
