I have ec2 instance on AWS, what I want it's to use IP from server outside AWS on this instance.
I can setup VPN on server outside AWS and use it with ec2 instance for example.
But what is the better way to do it? Maybe use some VPN-Client service in AWS to connect to my vpn-server and route all traffic from ec2 instance to this VPN connection?
What is the better way to do it?
Thanks.
For this task I found that PROXY server is better solution then VPN

I have a Django web application, running on AWS Elastic Beanstalk, inside of an EC2 linux instance.
Only the load balancer is accessible to the internet, for security reasons. Deployment to the EC2 app server is facilitated by Elastic Beanstalk, but new packages added to the repository can't be installed without an internet connection.
What is the standard way to automatically update without an internet connection?
Should I just create another EC2 and use it as a proxy server? How can I configure this?
Are there any references on this topic?
Typically NAT gateway is used for that:
You can use a network address translation (NAT) gateway to enable instances in a private subnet to connect to the internet or other AWS services, but prevent the internet from initiating a connection with those instances.
There are also NAT instances which also can be used for the same purpose. However NAT gateway is a managed and scalable service and is usually preferred over NAT instances.
I have an instance and s3 bucket in AWS (which I'm limiting to a range of IPs). I'm wanting to create a VPN and be able to authenticate myself while trying to log into that VPN to get to that instance.
To simplify, I'm trying to set up a dev environment for my site. I'm wanting to make sure I can limit access to that instance. I'm wanting to use a service to authenticate anybody wanting to get to that instance. Is there a way to do all of this in AWS?
Have you looked at AWS Client VPN:
https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/what-is.html
This allows you to create a managed VPN server in your VPC which you can connect to using any OpenVPN client. You could then allow traffic from this vpn to your instance using security group rules.
Alternatively you can achieve the same effect using OpenVPN on an EC2 server, available from the marketplace:
https://aws.amazon.com/marketplace/pp/B00MI40CAE/ref=mkt_wir_openvpn_byol
Requires a bit more set up but works just fine, perfect if AWS Client VPN isn't available in your region yet.
Both these approaches ensure that your EC2 instance remains in a private subnet and is not accessible directly from the internet. Also, the OpenVPN client for mac works just fine.
I want to connect my (OSX) laptop to a VPC in AWS but I couldn't find a way to do this since I don't have a static IP.
Azure has managed P2S VPN: https://learn.microsoft.com/en-us/azure/vpn-gateway/point-to-site-about. Is there something like this in AWS?
You can stand up a virtual device (such as a CheckPoint firewall) in the VPC on an EC2 instance that has point to site VPN functionality. There are a number of AMI’s and quick starts for this available. You would also need a VPN client running on your laptop.
As an alternative, you can set up a bastion server and whitelist your IP. You can create a shell script that gets your IP and makes an AWS CLI call to update the security group with that value if it doesn’t exist. Then, log into the bastion and you’re in the VPC.
You can setup a client VPN under the VPC menu:
https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/cvpn-working-endpoints.html
It will require to have server cert, as well as client certificates or a link to managed AD for authentication.
I have created a redis endpoint on amazon elastic cache and also setup vpc & NAT gateway. I need to connect created redis endpoint with redis-cli. i using command like this
redis-cli -h dev-redis.434dffsdsf.0094.ustyue1.cache.amazonaws.com
But i got error message like this
Could not connect to Redis at dev-redis.a35gy4.0001.use1.cache.amazonaws.com:6379: Connection timed out
I tried with several ways
tried to connect from my local ubuntu machine.
tried to connect from a ec2 instance.
My source code is running on aws lambda. Using aws lambda we can successfully connect to the same redis endpoint.
What is the actual issue with my redis client?
Please check SG of ElastiCache. Redis instance should be accessible to server where you're running Redis CLI.
Option 1 will not work, as ElastiCache instances are not accessible outside of their VPC. From the FAQs: "Amazon ElastiCache Nodes, deployed within a VPC, can never be accessed from the Internet or from EC2 Instances outside the VPC."
Option 2 should work, if the EC2 instance is within the same VPC as the ElastiCache instance.
Adding more details as none of the answers here gave me full clarity
What is security group - security group in AWS is like a firewall.
What should I check in the security group - Check in inbound rules of the security group attached to the Redis if port 6379 is open to IPs within the CIDR (e.g. 192.168.32.0/20) of the EC2 instance from which you tried to access the Redis/ElasticCache
I have a tomcat app deployed onto multiple ec2 instances behind ELB ... Is there any way to access each instance using jmx? AWS provides any service for it??
Thanks.
Is there any way to access each instance using jmx?
If each instance has a public IP or Elastic IP, and the appropriate port in the Security Group is open, then you could connect directly, bypassing the ELB. You'll have to go around the ELB somehow in order to connect via JMX. I suggest using a bastion host and SSH forwarding.
AWS provides any service for it??
AWS does not provide any service specifically for this. This is just general networking, which is provided by the VPC service.
