Class Notes
SOHO Routers are better than residential routers, and easier to use then Enterprise routers
Always buy a static IP address if servers on the LAN will provide services to the Internet
DHCP is provided by most SOHO routers.
Create a DHCP scope that does not include the static IP addresses used by other servers on the network.
The DHCP server on a SOHO router can trigger other DHCP servers to turn off
Port Forwarding allows you to forward specific types on Internet traffic to specific servers on the LAN
Firewalls block ports which can prevent hacking, but can also cause problems for legitimate users

I love how you fully explain things and don't assume the audience knows. That's a gift of a good teacher.
-
You teach better than anyone I have so far found on YouTube. Thank you for teaching us. You are quite intelligent.
-
Not too easy, and the harder topics thoroughly explained: you are a natural born teacher!
-
Thankyou Eli, the computer guy. I truly appreciate this presentation since it answer number of questions that have been pondering my mind. Especially disabling DHCP on router when there is an actual DHCP server on the network and the DMZ technology. Thanks again.

Your videos not just educate but I literally enjoy learning from you sir. God bless you. ❤️ Please make a series on how to build a small network using manageable switch. So that we can actually see the professional or lets say a lab environment. Cheers

Thanks Eli for another understanding. You've made me understand more than what I've been thought in class. I'll keep watching your videos for more understanding
-
Awesome teaching classes! I have been watching your videos and I just started in the I.T. field. I have learn`t lots from you. Thank you and keep on making awesome videos Eli.

Eli, again great job. I will be doing is more than once. The router 'thing' always was a phamtom box to me. I now have a better understanding and will need to do this again. I do have some application questions for a specific need, but I will continue doing the videos to see if it is covered before I submit the question. Thanks again for your time.

I set up a static IP address a month ago for my home computer, it's very very useful.
-
Thank you so much Eli! I never knew you could have multiple External IPs from 1 modem
-
Guys you do a great job, for beginners and for advanced users too. I want to thank you a lot great job again!

port 3 some geeky company that do everything in the world......funny.... by the way great work... keep doing... it is helping students alot......

Mr. Eli, thanks for this lesson on SOHO routers. I learnt alot of cool stuff man.

虽然只能听懂部分，但加上板书真的不错，谢谢ELI。

Unline DHCP and DNS, you can layer multiple Firewalls on a network, which is how a DMZ works. The first firewall has very loose rules to allow the webserver and/or public access connections to work, but then the 2nd firewall with all your important systems behind it is a much stricter firewall that blocks everything that the first firewall allows that you don't want to have access to your important systems.

Cool, thanks! Nice to know I haven't completely missed the mark.
-
I lack words, you are the best.
-
Eli, You are doing a great JOB...Keep it up....Very nice videos
-
Very good stuff presented in a manner easy to understand by non network engieers

"start with 1 router then play with that, then use the DMZ routine.." hahaha i exactly did the same thing! but this caught me "using routers is as much art as it is science" :) that was awesome
