I setup a pfsense firewall for my home network and it works great, however, when it gets under a heavy network load it starts lagging. So when we start gaming, stuff like Planetside2, counterstike, and our xbox360 all at once, it's bad enough that we take the gaming pc's and xbox off the firewall then the lag goes away.
I looked at traffic shaping, but frankly, I'm kind of lost on how to use it. There is one thing that I realized that I could try. I use a 5 port switch to connect everything to my firewall, so I'm going to try hooking the cable modem and all the pc's to the switch. So if it starts lagging, obviously my switch is the problem.
However, I would bet that it isn't my switch. So if that plan falls through, is there a way to optimize my firewall? Or maybe is there a good explanation on how to use traffic shaping?
I have looked at the logs on the firewall, but I didn't see something that would indicate what the problem is. But, maybe I don't know what to look for. Is there something in the logs that typically indicates network lag?
by the way, my pfsense firewall is running on an old Dell. It's got a pentium 4 2.8ghz, with 2gb of ram. The network card is a dlink dfe-530+, the other connection is the on board nic.
