AWS Site-to-Site VPN now supports modifying tunnel bandwidth on existing VPN connections
Amazon Web Services has launched a new capability for its Site-to-Site VPN service that allows organizations to modify tunnel bandwidth on existing VPN connections without requiring a complete recreation of the connection. The feature enables customers to switch between standard bandwidth (up to 1.25 Gbps) and large bandwidth (up to 5 Gbps) while preserving all existing configuration parameters including IP addresses, CIDR blocks, and pre-shared keys. Previously, organizations needed to delete and recreate VPN connections entirely when bandwidth requirements changed, a process that generated new tunnel IP addresses and forced administrators to reconfigure on-premises VPN devices and update firewall rules. The new modification capability eliminates these administrative burdens by maintaining all connection settings during the bandwidth upgrade process. The feature is currently available across 23 AWS regions including major markets in North America, Europe, Asia Pacific, and other global locations. AWS positions this enhancement as a response to evolving organizational networking needs that require flexible bandwidth scaling for hybrid cloud connectivity.
Why It Matters
This update addresses a significant operational pain point for enterprise network administrators managing hybrid cloud infrastructure. The ability to modify VPN bandwidth in-place reduces network downtime, eliminates complex reconfiguration tasks, and provides more agile scaling for organizations with fluctuating bandwidth requirements. This enhancement makes AWS's VPN offering more competitive with other cloud providers and reduces the operational overhead of managing site-to-site connectivity at scale.
