Hey Guys. I dont know if many of you are involved with the networking side of things as much as I am forced to be, But if you need a solid, powerful cheap router, you should check out www.vyatta.org. It also has instrusion prevention, clustering, and various sorts of VPN ( IPsec/L2TP, OpenVPN, and PPTP).
It will run on x86 hardware, or like I do, inside a virtual machine. If you need help with setting it up, just post back here
