@OP - If you want to block P2P why not just use layer 7 filtering for the protocols, your solution with ques is elegant but to me seems more complicated than it needs to be...

Because afaik last time we tried it we couldn't make it work the way we wanted to, which is why we are going with a complicated solution for best results.

I don't get it... Why are you making a core , distribution , and access layer for 120 machines? You are not going to get any benefit either out of the distribution or core switch. You also realize since this is only going to be around 120 devices, this means one /24 subnet. That means there will not be any traffic going up to the layer three switch. Everything will be switched at layer 2.

I am also trying to figure out where the PFSense firewall is going to come in. The only thing I can see it used for is internet traffic. Remember the firewall would be the gateway or just another all zeros hop for the switches. No game play would make it to the firewall either.

I think we need more explanation on how exactly you want to set this up.

+1 to cacti...

With 100-120 clients on a single network, on those types of switches, and the data they'll be pushing. The network broadcasts get would loud. I'd subnet it out if I could, maybe /26. It'd reduce the chances of any dos attack that would take out the entire network. And in that case if an outage takes place, it's makes it easier to locate


I'd personally do a /26 and organize 4 rooms with ~ 30 people per room. This allows extra space for a person to have 2 IP addresses.. Computer/Laptop or File Server.

There will always be broadcasts though. I work with /22 client networks on a daily basis without issue. The only thing I would suggest to protect the internet and your servers is to probably just make a /24 for your clients (10.10.10.0/24) and then something small like a /28 for the servers, and put the PFsense as your gateway between the 2 subnets, forcing all traffic to travers the firewall. Just need to make sure the firewall is ready for Gbit+ speeds..

@Thorn-Blade: Basically we are going to have the switches in that order because it will be mostly internet play, we will only be hosting the composervers locally. The coreswitch we chose was chosen because of it's good reviews and it's stability it seeing as the Cisco we originally planned on using might overheat (and because it's Linksys rebranded.....). The pfSense will only be there to route traffic in/out of the premises during the event, and to act as a firewall to stop torrenting (as I expressed concerns about in the OP). The switches was also chosen because I have good experience with HP, they make good switches with good stability.

@wgman300: I am afraid I do not know how to subnet this. The ISP will (most likely) be giving us one /24 block of public IP's, nothing more and nothing less, this is what they have always done and it's been working quite good in the past (and on our previous events).

@herkalurk: The firewall (pfSense in this case) will be equipped with good quality Intel gigabit cards, might also purchase two more of them and trunk them together for 2Gbit and run load balancing over them to the core if needed.

As I said, I honestly have no idea how to subnet this stuff, any help will be appriciated, for instance, would this require change in our equipment (ordering of more switches), changing of the firewalls placement, the ISP's routing? The plan on the network is this:

ISP ---> Cisco switch (not ours) ---> pfSense ---> Core ---> Distribution-hall ---> edgeswitches on tables

You don't load balance, you'd channel-group....

- No need to break this up for broadcast storms. We use /24s in our enterprise data centers as do most large companies.

- As far as DOS attack goes... If it comes in from the outside, it will take down the entire thing no matter what you do on the inside. Do you really have an issue with someone on the inside kicking one of these off? I would think you would kinda know the people you invite or is this something open to the public?

You still have not explained enough to warrant a core and distribution switch..... In you diagram below, what "EXACTLY" is the Core switch there for?

ISP ---> Cisco switch (not ours) ---> pfSense ---> Core ---> Distribution-hall ---> edgeswitches on tables


You only need a collapsed core which combines the functions of a core and distribution switch. The only time you need a dedicated core switch is if you have multiple distribution blocks.

Proposed: ISP ---> Cisco switch (not ours) ---> pfSense ---> disto ---> edgeswitches on tables

You said you wanted something more complex from last time... Do you know what type of switching you are going to be doing at each layer? (Layer 2, Layer 3, or Layer 2/3?)
