Dan, I really appreciate your videos. Currently taking an ICND1 course and felt very lost with VLSM and ACL. Your videos are very helpful!
Dude... nobody has been able to explain to me how an ACL works as simply and as efficiently as you did here. Thanks a lot, it is very helpful. Suscribed, keep on the great work sir please !
Hey Dan. I am really getting to understand such complicated basic topics better when I look into your videos. Thanks a bunch for this. Keep rocking!!!

Very well taught. The calmness the method of teaching, no jumps slow simple and tough teaching thank you.
11 years later, a CCNA aspirant is thankful for this video. Still helpful to this day!

Excellent tutorial! You have a very clear and simple way of explaining this process. Really enjoyed this tutorial. Thanks!
This is the best job I have ever seen about Cisco, access list , professional way in going step by step.
Dear Sir, I took the CCNA exam on the 10/July scored 933/1000. Your lectures were extremely helpful especially the ones for topics such as ACL, NAT & Frame Relay which were difficult for me. If i didn't listen to your videos I would not have known anything about these topics. Thanks Sir.

Looked at 6 different explanations on ACL's.

Also, if u put in "do show run" in the config terminal u can also see the configurations without leaving the config terminal al the time.

You are amazing, so much better than my University professor which apparently teaches CCNPs..
best tut about cisco I seen so far in youtube
I enjoyed this video, you explained the subject in a way that is easy to understand. Thanks!
Great lab! I'd like to add that you make sure the cable connecting the two routers is a copper roller cable (the dotted straight black line) or the routers will not talk to each other.
Clear and great description of ACL configuration, Thanks
The clearest Explenation on youtube 5 stars man :)
2020 and still watching your videos
Amazing explanation.
God bless you sir.
Simple and easy explanation, Awesome! Thank you!
Your videos are great!
Thank you from Austria ;)
This content help me to learn ACL more, thanks a lot
you use a 0.0.0.0 in the wildcard if you want to have the access list apply to only one host as opposed to a range of hosts like 0.0.0.255 which applies to 256 hosts (254 usable)
intead of using a wildcard you can specify a host using the host keyword before the IP address like host 10.0.5.1 etc.
your videos are the best, easy to understand thank you and keep it up
Excellent tutorial, really helped. Many thanks
Thanks dude. You made it easier to understand.
Awsome tuto! I'm french and i understood everything :) Thanks mate
Lol while i dont understand shit that French natives say :')
hi, thank you for the tutorial. I am just learning right now and I would like to know if I deny more than one, two, or three do I need a new list or it can go in the same list, thank you Frank.

very good explanation please let me know if you have any other video that is related to CCNA
Thankyou so much for your explanation 💕
Does this change at all when VLANs are involved? I'm running the configuration just like the video says but when I apply ip access-group 1 out to vlan1 my source that I'm trying to block which is on vlan3 subnet can still ping hosts on my vlan1 subnet.
thanks man u explained well b4 i confused.
OMG lifesaver! thank you so much!
I still did not understand the outbound/inbound part. Coming out of the router, what does that mean? By how I understand, shouldn't it be inbound on the standard? Since it blocks forbidden connections?
edit : tried again and it worked. ty
thanks for your video, my question is that if you deny as in your example the ping from the .2.101 to the .1.100 , should the ping works on the inverse side (from .1.100 to .2.101) or shouldn't ??
Easy explanation: Tony represents 192.168.1.100. Chuck represents 192.168.2.101. They're in two separate rooms and Tony has his Access List Earbuds on full blast. Chuck yells out HEY!! but Tony can't hear him (Destination Unreachable). Tony yells out HEY!! and Chuck responds WHAT, A-HOLE but a-hole Tony never took out his earbuds so as far as he knows, Chuck didn't hear him (Destination Unreachable). Pings use ECHO REQUEST and ECHO REPLY. ACL prevented 1.100 from hearing 2.101's REQUEST. On the flip side, 1.100's REQUEST was received by 2.101 but ACL prevented the REPLY from reaching back.
Thanks for explaining well
tanx alot wid diz tutorialz it really helped me alot........
okay i did the whole thing exactly as you said. but what if you want to change the deny service back to permit?
you are awesome !!! thanks a lot for the tutorials !!!
Nice tutorial though!!
How can I implement this into my project when static route do not support VLSM
Wow Sir....Super Easy....:) God Bless You
Dan is the best!
i have a question, when i was taking my ccna cert, i was on acl and i couldnt config the acl in cause it kept telling me that it dosent need this configuration to complete the simulation. can you help me
At 12:09, can we use inbound so traffic coming from 192.168.2.101 will be block.
Hi Dan, thanks for your tutorials, i found them great and I understood lot of new things, I didn't only understand well the difference between inbound and outbound, could you explain to me? Thanks in advance :)
Awesome explanation...thank you!
Is the only way to do this , using access list only? What about Eigrip and OSPF? Please answer me sir.. Thank you.
You'r great.. smart explanation
u could also aply that acces list on F0/0 with the Inbound option??? Would work to?
