Lightboard Lessons: BIG-IP Life of a Packet
In this episode of Lightboard Lessons, Jason updates an earlier Whiteboard Wednesday with a slight change in flow introduced in TMOS version 12.1. Some of the features in this flow are only applicable if you have hardware or if you have security licenses applied. If that is not the case, just assume a PASS for those blocks.

Is there a nicely formatted downloadable picture of the final diagram?
Also, it would be great if F5 supplies closed-captions or a transcript (since YouTube's auto-CC isn't accurate.)

Hi @epaalx, I updated the article above with the drawing I used in prep for the video. Thanks for the feedback on cc/transcript, we'll look into that.

Both this and previous video refers to "HUD Chain" but I am unable to find precise definition. Can you define or provide reference?
- JRahm
The HUD chain is the just the protocol filters that trigger on both sides of the proxy. So for example, if you have an https application, you will for sure have tcp, ssl, http filters trigger on the client side of the proxy, then http, ssl, tcp in reverse on the server side of the proxy. HUD is a tribal knowledge name for the proxy from the movie Hudsucker Proxy. :)

Thanks Jason. Am I able to get a printout of "filters triggers", such as those associated with a VS, for instance?

A full size pdf of our iRules events is available at the bottom of this article.
 
Thomas_SchockaeJason, you could have, at the very least, used a blue colour for the HUD Chain block's background. :D ;)

Sorry man!
Lucien_55928Great chart Jason. 2 Questions: 1: Which path would traffic take If you have a NAT? 2: Which path would traffic with port lockdown on self/floating IP?
