Connect private networks of accounts via a global router

If your infrastructure is located in different accounts, you can connect the private networks of these accounts. A global router is used for this connection.

How it works

To connect private networks, each account must have a global router. The private subnets that need to be accessed from another account are connected to the global routers. After the connection, the subnets on the routers will be in the same address space, so their addressing must not overlap: the IP addresses of each subnet must not match the IP addresses of other subnets.

We connect global routers and their routing tables upon request. Once connected, you can route traffic between all subnets that are connected to the combined routers.

Connection example

You need to connect private networks in two accounts:

  • in account 1, private subnet 192.168.0.0/24 is connected to the global router. IP address 192.168.0.2 is assigned to the dedicated server, and IP address 192.168.0.1 is assigned to the global router as the gateway;
  • in account 2, private subnet 172.16.0.0/24 is connected to the global router. IP address 172.16.0.2 is assigned to the cloud server, and IP address 172.16.0.1 is assigned to the global router as the gateway;
  • global routers in the accounts are connected.

For servers to be able to exchange traffic, you need to:

  • connect the global routers;

  • configure routes:

    • on the dedicated server — to cloud server 172.16.0.2 via gateway 192.168.0.1;
    • on the cloud server — to dedicated server 192.168.0.2 via gateway 172.16.0.1.

Connect private networks of accounts

  1. Make sure that each account whose private networks you want to interconnect has a global router. You can view the list of routers in the Control panel: in the top menu, click Products → Global router. If the account does not have a global router or you want to use a new one, create a global router.

  2. Make sure that the private subnets you want to access from another account are connected to global routers. You can view the list of subnets in the Control panel: in the top menu, click Products → Global router → router page → Networks tab. If necessary, connect networks and subnets to the global routers.

    Subnets on the connected routers must not overlap: the IP addresses of each subnet must not match the IP addresses of other subnets.

  3. From each account, create a ticket. In the ticket, specify:

    • account numbers whose private networks need to be interconnected. You can view the account number in the Control panel in the top right corner;
    • IDs of the global routers that will be used for interconnection. You can copy the router ID in the Control panel: in the top menu, click Products → Global router → global router page → copy the ID under the router name.

  4. Wait for a response to the ticket confirming that the global routers are interconnected. In the Control panel, under Global router, the interconnected global router will have the Other account tag.

  5. To configure connectivity between devices located in the private subnets of the interconnected routers, set up static routes on the devices. You do not need to configure routes on global routers.
