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

Private network the server in the A-DC and dedicated server across pools you can through Selectel global router.

Principle of operation⁠

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

    • FortiGate number in the A data center in the format of neXXXyou can look at control panels in the device card;
    • local port number on 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 the global router to a dedicated server and to a FortiGate in the A data center. When creating a 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 the section Network → Interfaces.

    2.2. Press Create New → Interface.

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

    2.4 In the field Address enter an IP address from a private subnet, e.g. 192.168.100.1/24.

    2.5 In the field Interface members 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 the section Network → Static Routes.

    3.2. Press Create New → IPv4 Static Route.

    3.3 In the field Destination enter the CIDR of the neighboring segment.

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

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

4. Configure local ports and routes on the dedicated server⁠

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

  2. Write the routes.
