Tailscale 4via6 – Connect Edge Deployments at Scale

a year ago

Tailscale 4via6 subnet routing addresses connectivity challenges in edge and customer network deployments.
Common connectivity problems include multiple NAT layers, restrictive network policies, and fixed CIDR ranges.
Three approaches to tackle these challenges: consolidation, dedicated sub-network, or bypassing existing infrastructure.
4via6 supports network-in-a-network approaches, ideal for complex deployments like cameras, sensors, and robots.
Site-to-site VPNs are not suitable for edge infrastructure due to CIDR overlaps and lack of public IPs.
4via6 enables seamless connections between identical networks without managing IPs, CIDR ranges, or ports.
Key requirements for ideal setup: isolation, customer-wide connectivity, and secure remote access.
4via6 works on any internet connection (LTE, 5G, satellite) and integrates with Tailscale's fine-grained ACLs.
Use case: robots and autonomous vehicles benefit from 4via6 for unified network management.
Devices can be accessed via MagicDNS names or IPv6 addresses, simplifying connectivity.
4via6 also supports cloud deployments, linking VPCs across environments with overlapping CIDRs.
Available on all Tailscale plans, with enhanced security features on Premium and Enterprise tiers.
