Read more at: networkdirection.net/articles/routingandswitching/gretunnels/advancedgre/ Try the lab: networkdirection.net/labsandquizzes/labs/lab-gre-tunnels/ IMPORTANT UPDATE: I mention that there is a need to allow GRE through the firewall. This is only necessary if the tunnel is not encrypted. If we apply IPSec, as done in this video, the firewall will not see the traffic as GRE traffic. It will only see IPSec traffic, so you will not specifically need to allow GRE. (Thanks to Juergen from the Cisco Learning Network for pointing this out)
Thanks, this is really good feedback. Sometimes I think I overuse the router CLI in some videos. That's why I only used it a bit this time. Do you think this is better?
Network Direction well, the thing is you have to recognise the level of your audience. I think the level of your videos are more ccnp and above ( thats why I follow your channel) for this sort of audience, CLI is music to their ears and they won’t get tired of it. I like the fact that in your videos, you are trying to cover areas in networking which are more grey and although heavily used, still there are alot of confusion around them. This sort of topic is tight to CLI. Well done
That's good to hear. I was thinking that most of us see the CLI all day every day, so it might be nice to use it sparingly. I was concerned that I overuse it at times (the VRF videos for example). I appreciate the feedback, thanks
YES! I very much want to do something on DMVPN. I've started making notes. It might take a few weeks (I have some other videos in production), but keep an eye out and it will happen!
Awesome video, could you do another where you do a configuration but with IKEv2? As far as I know, IKEv2 is the new standard and I'd like that to be explained, since I don't think that I have understood it fully.
Clear, Concise, and, say it with me, HOLISTIC. Good job.
I love the way you explain using animation ..its better way to understand and also build imagination
You make topics look simple..excellent
Thanks!

Very informative video. Nicely done with enough coverage. I loved the section which you went on actual the router and started highlighting. Thanks

This is a GEM , Unexplored and untouched :D Great Tutorial . Simple and elegant
This is great video and in it there are well defined materials. Thank you for making a video like this
You're welcome!
really the best explaination on ever on GRE and IPSec,,, keep it going > new subscreiber
This is the best guide I've found on the topic yet. Any chance for a video or article on DMVPN?
YES! I very much want to do something on DMVPN. I've started making notes.
It might take a few weeks (I have some other videos in production), but keep an eye out and it will happen!
Excellent guide! Thank you very much! Please keep up with the good work!
I'm glad it's helpful to you!
Another good guide. Thank you for the video.
Glad you like it! Part 3 out tomorrow
So helpful and clear. Thanks!
You're welcome!
Excellent video as usual :)
Thanks Ali!

Yes, IKEv2 is better, although not used as often as it should be.
I've added your request to my list. I'd like to update this with IKEv2 content.
Great video!
Learnt lots again!
Glad to help Daniel, thanks!
08:28 UDP port 500 is for isakmp.
Btw good job.
You're exactly right, I misspoke. Protocol 50 is ESP, USP/500 is ISAKMP
Unfortunately UA-cam won't let me add a correction
Excellent video.
very nice .... this helps a lot, cheers
You're welcome!
👏👏👏very nice. thanks.
Excellent
Thanks!
Good ol’ IPSec :-)
