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

Within one pool a server hosted in the A data center, and dedicated server can be combined into a private (local) network at the L2 level.

Network connectivity is ensured by means of firewall which is housed in the A data center, and Selectel network equipment.

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

Dedicated servers (except 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, go to control panels on the server page → tab Ports. The server in the A-DC does not connect to Selectel LAN switches by default, but connects to the firewall directly.

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

A private network scheme between a server in the A-DC and a dedicated server:

Network a server in an A-DC and a dedicated server in a private network⁠

  1. В control panels create ticket with a request to organize a private network between devices. Specify:

    • identifier a dedicated server;
    • number firewall in the A data center. The number is listed on the device card in the control panels in the format (neXXX);
    • local port number on firewall to connect.

  2. Wait for an answer about organizing a private network in a ticket.

  3. Configure the firewall.

  4. Configure a dedicated server.

To configure a FortiGate⁠

Configure the IPv4 address of the private network to be used as the default gateway.

  1. Open the FortiGate web interface.

  2. Go to Network → Interfaces.

  3. Click Create New → Interface to create a new logical interface.

  4. Specify Type — Software Switch.

  5. In the field Address Specify the desired IP address from the private subnet, e.g. 192.168.100.1/24.

  6. In the field Interface members 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.

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 from the private subnet range that is specified in the field Address when customizing firewall.
  2. Set the interface address firewall as the default gateway.
