Facts read from this source

• Site to site definition Report an error

  “Site-to-site networking (also known as layer 3 (L3) routing) creates a bridge between two or more distinct networks, letting devices in different subnets communicate with each other without a direct connection.”

• Site to site mechanism Report an error

  “You can create a site-to-site connection using Tailscale subnet routers, which lets you connect entire networks (such as different physical locations or cloud environments) together securely through your Tailscale network (known as a tailnet).”

• Client not required on devices Report an error

  “Now a device in subnet A can connect to a device in subnet B (and vice versa) without either needing to install the Tailscale client.”

• Subnet router os requirement Report an error

  “Both subnet routers must use a Linux-based operating system.”

• Overlapping cidr limitation Report an error

  “The subnets must not have identical CIDR ranges. If you need multiple subnet routers advertising the exact same subnet (for example, two routers both advertising 10.0.0.0/24), use high availability or 4via6 subnet routing.”

• Longest prefix matching Report an error

  “Tailscale supports subnet routers advertising overlapping routes with different prefix lengths. When multiple subnet routers advertise overlapping subnets, Tailscale uses longest prefix matching (LPM) to route traffic to the most specific route available.”

• Snat disable flag Report an error

  “Disable source network address translation (SNAT) --snat-subnet-routes=false (Linux only)”

• Subnet router approval workflow Report an error

  “you must approve it from the Machines page of the admin console. If you used an auto approver policy in the tailnet policy file for the device, you don't need to approve the subnet router manually.”

• Key expiry disabled with tags Report an error

  “You might prefer to disable key expiry on your subnet routers to avoid having to periodically reauthenticate. If you are using tags, key expiry is disabled by default.”

• Policy update required Report an error

  “You must update the access control policies for your tailnet to allow communication between the subnets by creating access rules (grants) to permit the subnets to connect.”

• Policy editors Report an error

  “You can do this from the Access controls page of the admin console using either the visual editor or the JSON editor.”

• Ha accept routes caveat Report an error

  “For most HA subnet router setups, use the --advertise-routes flag alone. Avoid using --accept-routes unless you specifically need that routing behavior.”

• Mss clamping recommendation Report an error

  “You should also clamp the maximum segment size (MSS) to the maximum transmission unit (MTU). You can do this using iptables.”

• Accept routes flag Report an error

  “Accept routes --accept-routes The --accept-routes flag accepts the advertised routes of all other subnet routers in the tailnet.”

• Advertise routes flag Report an error

  “Advertise subnet routes --advertise-routes=<CIDR> The --advertise-routes flag specifies a CIDR range of the IP addresses to be exposed to the tailnet.”

• Cloud route table option Report an error

  “If the subnet is in a cloud environment, such as AWS, you can usually update the cloud provider's routing tables instead of configuring each device directly.”

• Ip route nonpersistent Report an error

  “The ip route commands do not persist after rebooting. You must run them again after each reboot.”
