How to create a minecraft server using Technicolor TC7110.d?

For this to work consistently, you either need to purchase a static IP on your internet connection, or use a dynDNS type service. Or just figure out what your external IP is every time you play and send it to your friend before he tries to connect.

The next step completely depends on exactly how your network is setup. Is it a modem + router setup, or is it a modem/router (one device only) setup. If it's the latter, you will need to login to your router and configure the ports. How to do that depends on the exact model number of the router. Then you have to assign a static IP to the server, and forward the ports from the router to the server. And possibly configure the servers firewall to let them in.

In other words, there are so many variables, we can't do much more then give you generic advice. More then likely there's no step by step for your exact setup. You'll need to figure it out on your own.

You Don't need no Static for this to work.

Just add the Port Forwarding Details.

Your MineCraft Server will update the Trackers on MineCraft listing sites… You Do NOT NEED A STATIC ADDRESS.

Verify the port is open, and note your external IP by using a port checker tool, such as You Get Signal. The default port you should test is 25565, unless you specified something else.

Here are other Options:

A Minecraft server does not need to be a high-end machine, but netbooks and notebooks don't usually make for good server machines. They typically have lower-end hardware and bad I/O performance in comparison to desktops computers.
Hosting and playing on the same machine is also possible, if your computer is powerful enough.
Having many players in a wireless network (WLAN and especially WWAN) is not recommended. Use a wired network instead, such as Ethernet.
If you decide you don't want to host, but still want to play online, check out the public server options in the Minecraft servers area of the Minecraft forum.
If you still want to manage a server, but not from home, check out the Minecraft server hosting area of the Minecraft forum or other websites. Expect to pay monthly for this type of server since finding free hosting is a rarity. But you save the hassle of constantly maintaining a server and having is on-line for your players.
