In today’s dynamic business environment, cloud computing has become a crucial enabler, offering enterprises unmatched scalability, flexibility, and cost-efficiency. Amazon Web Services (AWS), a leading cloud service provider, has transformed how organizations manage their IT infrastructures and applications. With AWS Virtual Private Clouds (VPCs), businesses can establish secure, isolated environments within the cloud, replicating the capabilities of traditional on-premises networks. However, despite the clear benefits of cloud adoption, bridging the gap between on-premises networks and AWS VPCs can be challenging, particularly when dealing with overlapping IP addresses. Situations often arise where on-premises networks and AWS cloud environments unintentionally use the same private IP addresses, obstructing communication and data exchange across the VPN tunnel.
This article addresses this specific issue and explores an innovative solution for establishing secure connectivity between overlapping on-premises networks and AWS VPCs. Leveraging AWS site-to-site VPN, the traditional method for connecting on-premises environments and VPCs, enterprises frequently face obstacles when managing conflicting IP addresses. Mergers, acquisitions, and other networking complexities further complicate the situation, making straightforward resolution difficult.
