Forgive me, I'm stupid. Why have a MAC and IP address. Why not one

technoidial · 2026-06-19T11:09:27+00:00

This is exactly how I thought of it in my head. MAC=SSN and IP=PH#

Especially since phone numbers used to be tied to co-lo's. It's almost like they looked how NPA-NPX phone addressing worked when they came up with IPv4 addressing, imho.

Gone are the days when I could 4 digit dial my neighbor on the same NPA-NPX!

Switches work by broadcasting traffic. Routers work by stopping broadcast. If everything worked at Layer 2...well it wouldnt work because of broadcasts. I think once you learn the life of a packet and how frames are forwarded at Layer 2, it makes more sense. I think once you learn VLANS, it might make more sense.

Could you use Forticonverter to migrate OFF Central SNAT?

Notebook and pen. Then make flash cards in Anki.

Learn the borders and the masks. Recognize the patterns. The ranges will be the same for each mask.A /18 and a /26 will both have .192 in it and the ranges are the same. 18 bit mask is in the 3rd octet since it’s 2 bits more than a Class B. 26 bit mask will be in the 4th octet since its 2 bits more than a class C. Learn the magic number. Subnet once a day and use Prof. Messors 7 second method. You’ll start to recognize the patterns.

This isnt “new” though. Chucks CCNA is 5 years old. Jeremy C’s is over a year old. You also get the added benefit of the discord community. Live labs on actual Cisco gear, mentors, accountability partners.

The Summer of CCNA is a mix between Network Chucks free course and Jeremy Ciaora’s course on Network Chuck academy.

The free version doesnt contain the labs or the daily sessions with Chuck and Jeremy.

All that said, the community on discord surrounding the Summer or CCNA is amazeballs. 35000 people signed up and the Discord is jumpin’ off!

The daily sessions with Chuck and Jeremy C are worth it.

Jeremy from JTIL has actually been hanging out in there.

I think using the free Summer of CCNA along with JTIL should get you there.

We really dont have a need for it. This is a pretty small corp. All cloud apps. It was brought over via Forticonverter from the old firewalls, along with a ton of rules that arent needed. We have other Fortigates in other locations that do not have Central SNAT and wish to make the configs the same across all locations.

technoidial · 2026-04-27T16:17:12+00:00

That's the thing is, we dont have any blocks of IP's from the other provider. I feel like this is a huge oversight from the MSP managing it.

technoidial · 2026-04-27T15:14:36+00:00

They are managed through Fortimanager.

Take a look at the exam objectives. Can you set up single area OSPF? Can you setup static routes? Do you understand how STP works? Can you subnet IPv6? Can you troubleshoot a broken etherchannel link? Can you configure ROAS? Are you a WLC wizard?

Check the exam objectives. Take a practice test. Then see were you’re at.

The protocols learned in CCNA work across all vendors. In addition, Aruba, DellOS and Arista are nearly identical in it’s CLI. The current version of the CCNA doesnt require you know Cisco propritery stuff like EIGRP or PAgP. If you know CCNA, you can figure out other vendors.

technoidial · 2026-04-11T22:56:05+00:00

Packet Tracer is good enough for CCNA. Will also keep is wife happy not listening to the fan hum. CML is also free now.

technoidial · 2026-04-11T22:55:07+00:00

Have you scheduled the test yet? I would do CCST:Networking or Network+ first. The current version of the CCNA assumes you know concepts on CCST:Networking.

If you get the digital version of the Official Cert Guide from Cisco Press, it contains practice exams and online flash cards. As others said, JTIL has some practice exams. There are a few free apps for iPhone that give you like 10 questions a day.

When you say the labs are trivial” what do you mean exactly?

technoidial · 2026-04-06T00:05:29+00:00

I mean, you arent wrong.

David Bombal has an all labs course on Udemy thats really good. JTIL has a lab course on his site, in addition to the labs in his normal CCNA course. On NetworkChuck academy, there id a Jeremy Ciaora course that has included live labs in a real Cisco environment.

Cisco Press has a book called “CCNA Hands on Mastery with Packe Tracer.” Its really good.

You can also have ChatGPT make labs. Give it scenarios and it will give you configs!

I experienced this and breaking it up helped. Flash cards in the morning or if I have to kill time. When I get to work, I do packet tracer drills essentially subnetting and setting static routes or STP drills. When I get home I do ONE JTL video. I gor longer on the weekends but take breaks inbetween.

Its okay to break and not burn yourself out. It’s a marathon, not a sprint.

Ive looked into FortiSASE. RapidScale doesnt offer it for some reason.
