I have followed this :Connect to Neptune on AWS from local machine
Instead of changing this file C:\Windows\System32\drivers\etc\hosts, I changed C:\Users\user_name.ssh\config file as below:
Host 10.100.128.00
Hostname 10.100.128.00
Port 22
User ec2-user
IdentityFile ~/.ssh/my-ec2.pem
then I ran: ssh -L 8182:<neptune endpoint>:8182 <bastion server ip>
Now the status check worked but how can I use this connection to achieve other things(create vertices/edge) in Neptune? Can someone help with that?
