Combine a server in an A-DC and a dedicated server from different pools into a private network

You can privately network a server in the A-DC and a dedicated server from different pools via a Selectel global router.

Principle of operation⁠

To connect to the global router, the dedicated server and firewall must be connected to the LAN switches in their pool and have a local VLAN defined on their ports.Dedicated servers (except for some Chipcore Line servers ) are connected to the LAN switches by default.The firewall will be connected to the LAN switches for free when organizing the network through the global router.

Configure private connectivity between a server in the A-DC and a dedicated server from different pools⁠

  1. Connect the firewall to the LAN.
  2. Organize a private network through a global router.
  3. Configure the firewall.
  4. Configure local ports and routes on the dedicated server.

1. Connect the firewall to the local network⁠

  1. Create a ticket To connect the FortiGate in the A data center to the LAN. Specify:

    • The FortiGate number of the FortiGate in the A data center, in neXXX format, can be viewed in the control panel in the unit card;
    • The number of the local port on the firewall to connect to the LAN switch and the VLAN for that port.

  2. In the ticket created, wait for a Selectel employee to respond that the firewall in the A-DC is connected to the LAN.

2. Organize a private network through a global router⁠

  1. Create a global router.

  2. Connect the network and subnet to a global router to the dedicated server and to the FortiGate in the A data center. When creating the network to the FortiGate, select the Dedicated Server service and specify the desired VLAN.

3. Configure the firewall⁠

  1. Connect to the FortiGate through the GUI.

  2. Create and configure a local interface with a dedicated subnet:

    2.1. Go to Network → Interfaces.

    2.2 Click Create New → Interface.

    2.3. In the Type field, select the interface configuration type — Software Switch.

    2.4 In the Address field, enter the IP address from the private subnet, for example 192.168.100.1/24.

    2.5 In the Interface members field, add the physical port that is connected to the server in the A data center.

  3. Add a static route to the neighboring segment on the local interface:

    3.1. Go to Network → Static Routes.

    3.2 Click Create New → IPv4 Static Route.

    3.3 Enter the CIDR of the neighboring segment in the Destination field.

    3.4 In the Gateway Address field, enter the IP address of the gateway you specified in step 2.4.

    3.5. In the Interface field, specify the local interface you created in step 2.

4. Configure local ports and routes on the dedicated server⁠

  1. Configure local ports to work with the created global router subnet. To do this, change the network settings on the dedicated server.You do not need to boot the server in Rescue mode and mount the OS file system.

  2. Spell out the routes.
