Private network a server in an A-DC and a dedicated server from the same pool

Within the same pool, a server hosted in an A-DC and a dedicated server can be combined into a private (local) network at the L2 level.

Network connectivity is provided by a firewall, which is housed in the A data center, and Selectel networking equipment.

Principle of operation⁠

The dedicated server and the firewall are connected to Selectel LAN switches and a common VLAN is assigned to their ports.Direct switching with the firewall is possible only for servers that are located in the A data center.

Dedicated servers (except for some Chipcore Line servers) are connected to Selectel LAN switches by default and are included in a dedicated VLAN.To see which VLAN is assigned to a port, you can see which VLAN is assigned to the port in the control panel on the server page → Ports tab .The server in the A-DC is not connected to Selectel LAN switches by default, but connects to the firewall directly.

When requesting to network a dedicated server and a server in the A-DC, a port on the Selectel LAN switch is allocated for the firewall and the same VLAN as the dedicated server is assigned to it. The port for the firewall is allocated free of charge.

Configure private connectivity between a server in the A-DC and a dedicated server in the same pool⁠

  1. Organize a private network between devices.
  2. Configure the firewall.
  3. Configure a dedicated server.

1. Organize a private network between devices⁠

  1. Create a ticket with a request to organize a private network between devices. Specify:

    • The dedicated server identifier (UUID) can be viewed in the control panel: in the top menu, click Products → Dedicated Servers → Server Card;
    • number of the firewall in the A-DC, can be viewed in the control panel on the device page;
    • The number of the local port on the firewall to connect to.

  2. In the created ticket, wait for a Selectel employee to reply that the private network between the devices has been organized.

2. Configure the firewall⁠

  1. Connect to the FortiGate through the GUI.

  2. Go to Network → Interfaces.

  3. Create a new logical interface by clicking Create New → Interface.

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

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

  6. In the Interface members field, add the physical ports that have connectivity:

    • to a server in the A data center, which is aggregated into a private network;
    • to a Selectel LAN switch.

3. Set up a dedicated server⁠

The LAN for the dedicated server is fed to the network interface with the highest MAC address value.

  1. On the network interface of the dedicated server, configure a private IPv4 address from the private subnet range that you specified when you configured the firewall in the Address field.
  2. Set the address of the firewall interface as the default gateway.
