How to safely run multiple dedicated servers on the same network?

post #1 of 10
Thread Starter 
I have setup ultra 50Mbps internet at my house. I am currently using it with my home computer, as well as a dedicated server for gaming and running a website. I've been playing with the idea of setting up 1 or 2 more dedicated servers to rent out to help cover the internet bill but i have a couple questions before i do this.

1. Security. I obviously wont want anyone having access to my home computer or to each others dedicated servers. Is this difficult to secure?

2. How could i set this up so each computer could setup their own port forwarding? My modem supports 4 connections (Cisco DPC3825). I was thinking about setting it up so the ports are all open on the modem, then give each dedicated server its own router that they can use for their port settings, unless there's an easier way. I know there is software out there to turn a computer into a router but i dont know what its capable of.

Thanks in advance for your advice!!

Unless you have a business line; it's probably agaisnt the TOS of your ISP.

Either way. Creating another VLAN would be the way to go. Restricting all server traffic to a single network.

That is a good point. I didnt think of the TOS. The internet plan 'Ultra 50 Business' though. It's wasnt originally intended for residential use as i understand it. Although it is something I would have to look into. Is VLAN like setting up a virtual dedicated server?

If it's a business plan they won't care about websites and constant running services because you pay the higher premium to do that. Of your new server, what will the 3 be running? 2 webservers and a game server?

If that's the case you will need a minimum of 2 public IP addresses because you can't have web requests coming into 2 server unless you do some port redirection. The router might understand upnp so the servers in effect could set up their own port forwards, but I would never use it. Do all of that manually. If you're concerned about security then you should know 100% what is on your network. Like killabytes said, use the cicso router to create a vlan for your home, and then a vlan for the servers. Then start restricting traffic between the 2 vlans for security.

I dont think they would be for websites, ill cross that bridge if it comes up though. I would be looking to rent it out mostly for running online game servers.

Speedtest.net result is Ping 16ms, 42Mbps down, and 4.65Mbps up. Im not sure what kind of rates you see in most servers, but i have yet to max this out and see lag issues from it. I've run servers for team fortress 2 with 32 players on it and saw no lag while also running a teamspeak 3 server, GMOD server, and Minecraft server, each of which had a few connections on it as well. What kind of speeds do you see from most servers?
