[TUTORIAL]Running a Server: Port-Forwarding, Hamachi...

====NOTE!! This does not show you how to make a server. It only shows the configuration required to get one working depending on how you want to use it. If you are starting from scratch and don't know what to do,view my other post here.====




Overview:
Once you've created your server, you'll no doubt want to let other people join. However, you may encounter a problem here: You start up the server, and it all works fine, up until someone tries to join. They simply can't. They either get a "Connection Time Out" error, or it will just stay at the Connecting screen.
There is a simple reason for this: Your network is not allowing the outside world to connect to your game.
To let others connect to your server, you can set it up in two ways.
Port-Forwarding, or Hamachi
Port-Forwarding will let other people connect to your server without any special programs required. It's how you connect to most servers.
Hamachi has the downside that everyone who wants to play on your server has to have Hamachi as well. This is troublesome, but is often used when one cannot port forward.

Hamachi:

1. You obviously need Hamachi for this to work. Hamachi is probably the easiest way to let people from around the world join your server. Download it here.
2. To run a hamachi server you need to configure your server.properties file as follows:
   • server-ip - leave this blank
   • server port - leave this as default (25565)
   • You may or may not have to set online-mode to false for it to work.
3. Open up Hamachi. If you have not already created a new network, do so now. This is what other users will use to connect to your network and join your server
4. When you give out your ip address for other people to join, make sure you use your hamachi one (should be something like 5.64.312.48)

Port-Forward:
To be able to play with other people around the world, without wanting to set up a server through Hamachi or a VPN, use port-forwarding. Port-forwarding simply allows you to host the server on your own PC and lets other people connect to your computer. This is useful since the players do not require any other program besides minecraft to play.

1. Server.properties file should be configured as following (same as Hamachi)
   • server-ip - leave this blank
   • server port - leave this as default (25565) (yes you can change it, but for newcomers leave it as default)
2. Step two can be done in two ways: The easy way, or the DIY way. Doing it yourself is not necessarily harder, but sometimes it can be a pain in the neck. If you would prefer an easy way to port-forward, see this page. The manual method is depicted below:
   • If you know your router's ip address (most likely something like 192.168.0.1), then type that into your address bar in your web browser.
     • If not, enter command prompt and type "ipconfig". scroll down to where it says IPv4 address. Type that into your browser, replacing the last number with a 1.
   • You will need to allow connection to the port 25565. This can be found under "Services", "Ports", or whatever your router calls the setting. You will need to open the port by doing as follows: (example using Netgear DGN3500 - should be similar for most routers)
     • Click "Add Custom Service" (or new rule)
     • Create a name for the service rule , e.g "Minecraft Port"
     • Select "TCP" or "TCP/UDP" as the type
     • The start port and finish port should be the same.
   • The next step is to configure firewall rules. GO into your firewall page on your router and add new rule. Select the service you created in the last step (for this example Minecraft Port) and set it to be always allowed
3. You will need to work out your external ip: this can be easily found here (note that this may change if your internet server assigns you a dynamic ip)
4. Now for how to connect:
   • If you want to connect to your own server, run minecraft.exe and type in "localhost" in the Multiplayer screen. This will allow you to connect to your server only if you are on the same system as the server.
   • All other players will need to connect using your external ip address.

This site gives a step by step configuration for each router.

You dont get it!!!
I know how to port foward, but the priblem is i CANT.
I do what you said, and ive doen it before, and it worked.
But when i type it in browser bar, it says page moved or down, its been like this for a month now :[ so i cant port foward if i can't get into my router's manager

Try going into =>Network Devices on your PC and double clicking on your router there

OMFG I LOVE YOU! This works perfectly and it's completely noob-proof. Thanks!
One tip though: You may want to add the information that when they enter their IP in their browser it usually asks for a name/password. For Netgear the default it "admin; password" and Lynksis I think is "admin; admin" other than that it's perfect and I love how it's 24/7. Thanks!

Yes I did thunk about adding that but then decided: meh they'll find out When they do it

One problem, whenever somebody tries to get stuff..they take something (like wood or dirt) and it won't give it to them when they destroy the block..like it's supposed to go into your inventory but it doesn't. We're not too close to the spawn either. How do I fix this? Please help soon. Thanks

One more thing, anybody can do anything. Everybody can change time, spawn TNT, turn on god mode...anything. What can I do? Please help I really would like to get this fixed immediately.

it means they don't have any special priveleges on your server. Use permissions to allow them to do things
It could also mean that there is lag on your server, causing the server to take time before it realises someone is trying to pick something up

PROBLEM: My router isn't on the list for Portforwarding.com My router is a Linksys Wireless-G.

Follow the steps I posted then

I get this error message when I leave my ip blank:

but when I use my ipv4 it runs normally but I cant connect it says 192.168.1.150 lost connection

you might have to change online-mode to false

You need to connect to "localhost". everyone else will use your external ip

Yeah,I can connect but this is what happens when people use my external ip:

Any clue whats wrong?

My god. Your server port is 52170 but in the server.properties it is 25565. I must be blind did not see it before. Just change the 25565 to 52170

Okay,changed my port in sever.properties,I also portfowarded 52170 and I can connect using :52170 but when I try my external heres what happens now:

But does it make a difference if I tried to connect with a different computer last time,that may be the problem?

I've tried port forwarding and using hamachi but neither allow players to join my server. i'm using craftbukkit understandably and installed it with the recommended installer. Whitelist is off but no-one I know can join.

Is your router set to allow incoming signals on the port?

Did you follow all the steps properly?

Yes,port 25565 and 52170 are both open,but when the port 52170 was a diffent computer trying to connect,and port I get when I try off of my computer is 60299.

interesting... Try the website link and check that you set up your router properly
I'm a bit stumped as to how to help, maybe someone else can?

I used their port checker,both open,but what I dont get is the port you told me to use was from my sisters computer the one on the recent error is from my computer should I try to change the port to 60299?

Aha! Brilliant! It took me some finding to get to my router settings, I typed the Connection-specific DNS suffix, which gave me the right page. Using my IP didn't work.

Stickied yet?

No its not stickied, but its only a matter of time

Are there any other types of server setup people would like help with? please let me know

#Minecraft server properties
#Mon Jul 25 19:12:08 NZST 2011
level-name=world
allow-nether=true
view-distance=10

max-players=20
server-ip=5.9.240.65
pvp=true

server-port=25565

white-list=false

It starts up fine but if me or anyone wants to connect it doesnt work ! please help and yes my hamachi is open

remove the 5.9.240.65 and set online-mode to false

When i try to put my ip in to port forward it just says acess denied, doesnt ask for a username or pass, just acess denied.

k i have a question, when other people try to join my server they cant conect, were using hamachi and on the notepad file on server properties i put online mode false and i left the server ip blank and everything, this makes no sense, i installed bukkit using the new easy installer that you put up and i start the server, and i go in from my computer using localhost or using my hamachi ip, then im in the server, but then when i go in my other computer, or my friends who lives across the street and i connect to the ip that i have in hamachi that im running where the server is installed it just doesnt connect
