My New 25 Gigabit Firewall Testing Setup! - Cisco TRex Traffic Generator

Interesting tutorial. You included enough details to allow this to be very interesting, but not too many as to make it an aimless rabbit trail. Keep up the good work!

You should check out the open source program packet batch in XDP mode

cool

Great video, it's good to know what that device can do running OPNsense. Would you be open to testing it with say RouterOS x86, just to see how Linux fairs against FreeBSD on the same hardware.

Can it also emulate thousands of parallels tcp streams for testing state tables?

You can also use source routing to Seperate your client and servers to route externally that worked before netns (but namespace are probably quicker to set up).

Very interesting and well done all around. Such a self-contained and complete setup would cost thousands ready-made! Thanks for sharing!

I don't know what any of this stuff does. I used to enjoy this channel but I'm finding it now to be more and more specialised in fewer and fewer things. Time I think I wasn't here.

Really hoping Ubiquiti send you the new Fortress Gateway to test on this rig. It’s supposed to be able to route >12 Gb/s with IDS/IPS on.

I want the install TRex on my lab environment but I'm struggling with the installation. Do you have a good tutorial? The Trex website is not very clear for me. Thank you in advance

Your small packets are also simulating TCP acknowledgements. When looking at packet loss remember there’s a delay for ARP lookup during which packets may be lost. Doing an arp first so it’s already in the table avoids the delay/loss.
