Building a FreeBSD switch with commodity hardware

[Kurt Buff - GSEC, GCIH]

And the cool thing is that Juniper's are FreeBSD underneath the covers!

If you don't need something that is under contract, something like a juniper ex4200 can be had on ebay for ~$100. 24/48 1g ports. supports vlans, ipv6 just fine. also has firewall capabilities, but they're not stateful.

I have 10 to 20 1gbps Ethernet devices to connect to the switch and a single 1gbps uplink to the rest of the internet.

I also want to be able to expand my system at a later date if I need to be able to handle more devices on the local network so I'd need to be able to hook the two networks together somehow.
