These classes are awesome Eli, thanks.

[@riteshdhawan8383]

Eli is the Guru of Networking, whether its On-Premise or Cloud. Started explaining firewall from bare fundamentals and took us to the cloud.

Hey Eli, Did you think you were a network guy in your earlier years? Did you think that was your calling? All those years were just a road to prepare you for your mission. You have helped SOOOO many more people n businesses with your youtube classes than you did in a server closet. You contributed a lot to this world with your skill as a tech and teacher skills combined into one. Thanks Eli! Al

Burning the KZbin channel down with these tech videos! #stayepic

[@arjunajith5761]

Thank you for this class. Can next vid be about AD?

[@Albertux]

Nice doodle

[@charisadu9544]

Terrible diagrams but great explanation. Thank you my good sir.

If you are deploying Dell ReadyNodes at remote sites - adding to a current vCenter instance - then 10k/server is still a thing. So 20k for minimum cluster requirements. That’s a R440 build. R640 is more like 13k each - 26k for a cluster. Requirements are the key really.

[@chumpmu1]

And that’s w/o VMware licensing for ESXi (RoBo) and what you mentioned - NSX, which is even more expensive. Plus - whichever OS you use. If MS, then expect about 8k for “basic” virtualization - 2 VMs per host, so 4 total. Servers are still expensive! Getting to Azure makes sense when you have the pipes to do so.

[@brandonbert]

Is it Wednesday yet? I need some more Eli the Nostradamus Guy.

[@roberto663-v5m]

Do you believe that the next cool technology NGFW will be with eBPF

[@muchada1]

As a Zimbabwean, I can attest that we are nice people. We do not hack people!

[@vabhosha]

[@silence6605]

But if you block port 25 won't that prevent your users from sending out normal emails?

[@elithecomputerguy]

Email will actually be sent from your on-site email server such as Exchange . You create a rule to allow outbound from the ip of your email server… or many services such as gmail use an alternative port for communication… or if you are using gmail from your browser the port question is mute because all the email actually stays on googles servers

[@silence6605]

@@elithecomputerguy thanks

[@mohammedodeh7601]

7:58 did you mean to say inbound for the first one ?

[@nathanscarlett4772]

I got caught up on this, too. I believe so, yes

[@azured909]

Wow, no politics? What happened? You finally went back to your roots?

[@wilfredotorres6628]

Hi Eli, That's the reason most companies have admin rights allowing certain employers to have access only to certain places outside the net, or what you see most often is the company only employs the Intranet allowing only the internal work-related activities. No access to anything outside what the network allows you to view. So, you're filtered off porn sites, gambling sites anything that would be a distraction to work activities.

[@jimflagg4009]

If you internet connection is slow look at your firewall.

[@dakoderii4221]

Susan don't like this, Eli. You are talking about "walls" and that's a no-no! The fire part is okay though, as long as it's "mostly peaceful"'.

[@KevinFlynn_]

Just use Kaspersky

[@hex3n]

Stop with tech. Eli the food guy
