D-Link DFE-570TX and Broadcom BCM5821

I have just acquired a used 4-port D-Link fast ethernet PCI board from a seller on eBay. I have been looking for one of these for my ‘new’ firewall for ages and was about to give up.

The firewall is an old crate of a Dell GX240 with PCI slots but it still has plenty of grunt to do what I need without consuming too much power. It’s one of the old Dells that I bought years ago for peanuts that has been upgraded with a 2.6Ghz Celeron.

I have been experienting with a Broadcom crypto accelerator in pfSense and I was about to give up on the GX240 and move up to a newer old machine with PCI-X slots.

The BCM5821 already delivers 24x performance improvent on 2048 bit RSA in the 33Mhz PCI bus and I am intrigued to find out how fast it will go in a 64 bit, 66Mhz slot. Now that I have the D-Link, I will crack on with the original plan and save the PCI-X upgrade for later.

More to follow…
