🎬 Let's do Packet Tracer labs together - Static NAT, Dynamic PAT, Routing, Troubleshooting - PTL2

In this live stream, I'm going to walk through a Lab from Keith Barker's CCNA Packet Tracer labs. I'll discuss my way through the configuration and explain relevant protocols and commands.

Keith Barker's Packet Tracer labs are available here (Scroll down to "FREE DOWNLOADS"):

In this live stream, we're going to walk through the lab titled "Cisco PT NAT/PAT 2020-04-12". The most up to date version is available from Keith's website. But here is a direct download link:

Priceless keep them coming!!! Thank You!!!

Great Job! Very detailed and easy to follow! Thanks!

[JimiShady]

Thank you very much for this video too. As always, it was a very useful explanation👍

[larrycorbett]

great job, I was able to follow every step

[jonedhso]

Thank you very much for these videos. The way you explain things is so amazing. I wanted to ask if you have solved the Keith Barker's lab 'Cisco PT TShoot the Web Server from Dan' in one of your videos. I couldn't see that in your videos list. Could you please share the link if you have done it?

Weird. When I did show run | s router on edge-router, it DID already show a static default route. Right under network 10.0.0.0 0.0.0.255, it had ip route 0.0.0.0 0.0.0.0 23.1.2.254. What I find really strange is show ip route reflects gateway of last resort S 23.1.2.254 0.0.0.0 (default route) on my lab I'm doing AND on the lab on screen here (at 19:32), yet the on-screen isn't showing that route under show run | s router, while mine IS. How is that? 🤔

Another Comment: Just right before configuring the nat. If we trace a ping to the server from PC1 in simulation mode, the packet goes to access1 switch and then to the MLS2 then the edge switch. Not as I assume, the packet does not cross the edge switch to the edge router. instead, it goes only to the MLS1 and from there it goes back to the edge switch, and there it crosses it to the edge router. could anyone explain this behavior?

Everything was going well up until the DPAT @ 46:26 that ping didn't respond

[DikiciBurak]

which drawing tool do you use in this training Ed ?

[JohnEstrada-fptv]

i.e., there
could be retransmissions 4:42

Sir. You need to talk a little slower so people can follow you.
