This topic tells you what to do, but ill try to put it some other way.
Find out if your using a router, firewall, learn your network setup, learn your modem setup.
Find out your external ip at
www.whatismyip.com
Open runuo/misc/serverlist.cs in notepad or some other text editor.
Here is where you make a choice.
If you want to be a local only server put this in:
public const string Address = "127.0.0.1";
If you want other to be able to connec to it put this in:
public const string Address = "your external ip here";
If you choose to be local only ignore the next section.
If you choose to be public and you have a router/firewall you will need to forward the port 2593 to the computer running the server.
Router port forwrding is usually done by going to the router's ip and seting it up to allow tcp connections though a port range. You will need to visit your router manufacturuer's website to see how to do this. Most will tell you exactly what you need to do in the support section of that website. We are not your router manufacturer and I don't think you ever told us if you had one or what kind it was.
If you are using a software firewall you will have to allow runuo.exe to act as a server and to accept connections. Again you must look at the maker of your firewall. Each firewall is different and we do not know how to work them all here.
Once you have all that done you will need to setup your connection method. I suggest using uogateway. You can get it from
www.uogateway.com. Get the full version. Install gateway and run it. I will assume you are running your uo client on the same computer as your server. If you are you will need to setup a custom local server entry. Do this by click on the words create custom local serverlisting in the my servers section of uogateway.
Enter the following info
Name: Any name you want
Description : Doesnt matter
IP 127.0.0.1
Select remove encrption
Save you settings
That will place a server listing for your server in the my servers section of uogateway. Use this to connect.
For others to connect to you shard you would have to make a public server listing on
www.uogateway.com or give out your external ip to those who you want to connect.
This is a general summary. It assumes you are running the client and server on the same computer. If you would like more help you need to share more information.
