I assume your grandson would be playing on a "safe" computer. Is the minecraft server hosted locally or on a remote server? Will it run on a "safe computer"? Would it just work to put a temporary router between your main router and the Internet source? What is the current topology of your network? Computers -> Linksys -> Cable Modem? I would just put an old router or computer set up as a router between your main one and the cable modem if that's an option: Safe Computers -> Linksys -> Old Router -> Cable Modem Unsafe Computers --WiFi/LAN----^ If this old router is a computer, you can even set up the minecraft server on it and then everybody, even the "Safe Computers" can access it. If not, you can port foward on the Linksys like in the tutorial: http://minecraft.gamepedia.com/Tutorials/Setting_up_a_server#Port_forwarding I would also set the "Linksys" to be the DMZ for the "Old Router" just so that any UPnP ports from the safe computers still get back to them. Or is it something like Computers -> FiOS Router/Modem? This would be a harder topology to do, but you can still set up a three layer network like: Safe Computers -> Linksys -> Old Router -> FiOS Router/Modem Unsafe Computers --WiFi/LAN----^ All of this would probably be pretty plug and play as long as you set the IP address of the routers to different subnets. E.G.: 192.168.0.1 192.168.1.1 and 192.168.2.1 Randall Mason clashthebunny@gmail.com On Mon, Jun 22, 2015 at 1:21 PM, Joel <joelgroup@gmail.com> wrote:

But do have an 8 year old minecraft fan, so listening for any answers.

Folks,

My grandson wants to host a minecraft server party for his boy scout troop and my daughter and I are wondering how to ensure that the existing machines on her home network are not compromised given that the members of the troop will be bringing their own machinesand ethernet switchesalthough some may be running wireless.

I was wondering if you could give us some thoughts on how to set up the network. It is my understanding that the minecraft clients do need to get out to the internet to obtain a valid player name. I had thought ofsetting up a seperate Router/Lan for the party, disconnecting the existing router/lan from the wan and connecting the minecraft router/lan to the wan for the duration of the party.

Any thoughts out there?
