+[IPv6 support for AWS Site-to-Site VPN for outer tunnel IPs](https://docs.aws.amazon.com/vpn/latest/s2svpn/ipv4-ipv6.html)| Site-to-Site VPN now supports IPv6 addresses for the outer tunnel IPs on Transit Gateway and Cloud WAN VPN connections. This enables full IPv6 migration with IPv6 addresses for both outer tunnel IPs and inner packet IPs (IPv6-in-IPv6), as well as IPv6 outer tunnel IPs with IPv4 inner packet IPs (IPv4-in-IPv6).| July 1, 2025
