I'm taking a guess at this one, although I should know.

I think that the DHCP request will come from the client after EAP authentication takes place. The reason I think that is because only port 1812 and 1813 are open, and those are just for authentication purposes, so how would it get an IP?

That did get me to thinking though, when the Authentication Server is communicating with the AP, is it (the AS) sending the data by IP, and if so, is it the IP of the Ethernet port of the AP? That doesn't make sense. Maybe the AS is always on the same subnet, so, it will send it by MAC to the Ethernet port of the AP. Still doesn't make sense.

Hey, I think it would actually send it to the MAC of the Supplicant, which the AP will intercept. Yeah.. I think that is how it works. Stream of consciousness is so scary....

Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
