How do you make a Terraria server?

My friend wanted me to start one. Wondering if anyone knows how >.>

Start a server, when it loads run another client and you can use your ip to login i think

if im correct, you are correct

Okay thanks!

can i join your server?

Is there no dedicated server software??

Um... I do that and it says this:

Btw its only gonna be me and my friend (as of now)

Did you port forward to 31337? on UDP?

I'm also running this on a server separate from my computer but on the same network, the it said about the same thing when I ran it on my own computer and tried to log in.

I'm afraid I don't know what UDP is. I've only hosted one server before for MineCraft, and it wasn't very good. I'm afraid I'm kind of new to this.

Watch this, http://www.youtube.com/watch?v=Kp-R-eHiQco
Forward Port 31337 to UDP using this video to help.

What do I enter for IP when I'm in the router? My own? (A.K.A. My server's)

You dont need to do routing when you're working on a LAN. Only for internet connections. You probably have a firewall on the computer (windows firewall or other) and you need to open port 31337 on UDP and woul do TCP just to be safe.

Anyway I did what the video said, named it Terraria, set it to 31337 - 31337, set it to Both, and entered the end of my ip (102) into the ip line. Still says the same thing. What is wrong with it?

Tried running it on the same computer with it port forwarded, added ports to my firewall, turned my firewall OFF, and it STILL doesn't work. I'm at a loss...

Apparently since I'd need another copy of Terraria on my server to run said server, I'll have to run it on my main computer. So... Anyone know how I can get it to work?

i dont know what you insane people are going about what i do to run it is a programme which comes with terraria in the default directory for the game called "server start"

run through everything with that then run the game and go to host and play then get your friend to join using your local IP address the it should work

This thread was made the day of release.
Great job, you revived it.
