assign our local Ip address to access using openvpn

Create a subnet in your VPC and assign it a static IP range instead of using auto-assign.

Run the associate-client-vpn-target-network AWS CLI command to associate this subnet with your Client VPN endpoint.

aws ec2 associate-client-vpn-target-network --client-vpn-endpoint-id cvpn-endpoint-id --subnet-id subnet-id

When you connect your OpenVPN client, it will now get an IP address from the static range assigned to the associated subnet, instead of a dynamic address.
