Amazing!
Aws is so costly? it used to have unlimited data before?
Thanks. This was somewhat helpful. Couple of things made clear in the process
Hi
I know this question has been asked by
@Noam Lerner but your explanation seems a bit hazy for me to understand. This is regarding creating a Customer Gateway. Is the Customer Gateway an AWS component or a plain router at a Data center? From AWS documentation, it appears that the Customer Gateway is something that need setting up at a Data center which implies this is a router – But then why does AWS provide a component / resource called 'Customer Gateway'? Is the documentation incorrect? Also, is OpenSwan mandatory to be set up – is that acting as a router which you are mentioning at 14:00. If yes, do we require a 'Customer Gateway'? From your tutorial, I am assuming no matter what, a VPN connection always require creating a Customer Gateway on AWS side (when we already have a router in Data center) – pretty confusing when referring to AWS documentation – could you help clarify this?
sir how can we set up vpn from on premises to aws so as to have an ec2 windows server for active directory:? thanks.
Thanks so much T.T
Can I connect a third vpc to VPC A thorugh vpn and reach from VPC B(on premises data center)?
More than many thanks! awesome video! this just saved my life
Great work on this video. Very clear.
Perfect…!!! Super class…. Much appreciate your effort
I followed the whole steps but tunnel is not up after i start the ipsec service. The logs says :

Any idea how to fix it? Can you please provide your email id to examplesbdev@gmail.com
How can I use this to access private instances directly from my machine? I do not want to use Bastion host, I want to access the instances directly using their private IPs. My device is a personal laptop, and hence is not under a company's network or a firewall. Any recommendations? Thanks a lot!
this all setupcan be done in free tier account without incurring cost?
Thanks and required the document mentioned on the presentation,where to find it
very helpful video, thank you
Thanks for the video, Good Explanation. you told over the video ,Would you mind sharing the documentation you used? Thanks again.
Thanks for the great tutorial, now the VPN connection is configured through my another EC2 instance in different region. Can you please help me out how can i use the public IP address of CGW to access my private EC2 instance from browser?
thanks for this tutorial; I wondered if it's possible to make this communication uses the public IP
Appreciating your effort. Really useful video. Many Thanks.
Hi
I am getting no pre-shared key found for local-ip remote-ip, I have followed exact steps to configure, can you please help?

Thanks for making the video!
I'm wondering why didn't you put the customer gateway in VPC-B. Looking at the AWS documentation[1], seems like that's what they recommend.
I'm probably missing something – as your video shows that the VPN is up, so I thought to ask.
Also, let's say I'd like to setup the second tunnel as well – would that be done in a similar way?
Thanks!

If you follow the video then you can complete this practical, give your hundred percent and do not give up then you can complete this exercise. Good video and this practical made me more confident.
Again completed AWS VPN site to site practical successfully just follow the instructions and I am sure everyone would be able to complete it.Thanks Sir.
I have completed the practical and IPSEC service started successfully and I am able to ping private IP address of EC2 under VPC-A.Thanks
unable to start IPSEC service again , I don't know where i am making a mistake .when i type journalctl -xe
it shows error message as Sep 01 20:13:23 ip-10-200-0-102.us-west-1.compute.internal systemd[1]: Failed to start Internet Key Exchange (IKE) Protocol Daemon for IPsec.

nice video .Can you share the document please
Awesome video as always…….. ?
But can you kindly explain the reason for disabling the source and destination check on ec2 instance at the vpc B (i.e. customer assumed network)

I am receiving above message when I type service ipsec status, kindly help
@AWSTrainingCenter when checking the ipsec status its not showing the tunnel details
Please share the document
This is very nice and helpful. Thanks for making such videos. I am able to setup VPN following the same steps and able to ping from both the sides, like from AWS EC2 private instance to Openswan and vice versa. But I have made another EC2 instance in Openswan side and unable to reach that from other side of the VPN neither able to reach any ec2 instance in other side from that instance. Actually that is the purpose of Site-to-site VPN, can you please help how to achieve that with openswan.
Very thanks for the session. I have followed each and every step keenly. At the last minute i have got a error when i typed the command service ipsec start as"Job for ipsec.service failed because the control process exited with error code. See "systemctl status ipsec.service" and "journalctl -xe" for details" Kindly help me to overcome
Could you please share me the document
Thanks for the video, well explained. Would you mind sharing the documentation you used? Thanks again.
I am unable to start ipsec serice and receiving error message as "Redirecting to /bin/systemctl start ipsec.service

Hi Team,
I tried this complete lab. Thanks first of all for such a detailed video. But I am stuck on last step. My ipsec service is failing any solution.
