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 data center and a dedicated server can be combined into a private (local) network at the L2 level.

Network connectivity is provided through the FortiGate, which is housed in the A data center, and Selectel networking equipment.

The dedicated server and firewall are connected to Selectel LAN switches and a common VLAN is assigned to their ports. Direct switching with the FortiGate is only possible 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. You can see which VLAN is assigned to a port in the control panel on the server page → Ports tab. The server in the A data center does not connect to Selectel LAN switches by default, but connects directly to the FortiGate.

When you request to LAN a dedicated server and a server in the A data center, the FortiGate is assigned a port on the Selectel LAN switch and assigned the same VLAN as the dedicated server. The port for the FortiGate is allocated free of charge.

A private network scheme between a server in the A data center and a dedicated server:

Private network a server in A-DC and a dedicated server⁠

  1. In control panel, create a ticket requesting a private network between devices. Specify:
    • identifier of the dedicated server;
    • FortiGate firewall number in the A data center. The number is listed in the device card in control panel in the format (neXXX);
    • The local port number on the FortiGate unit to connect to.
  2. Wait for an answer about organizing a private network in a ticket.
  3. Configure FortiGate.
  4. Configure a dedicated server.

Configure 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 Address field, specify 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.

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 Address field when configuring the FortiGate unit.
  2. Set the FortiGate interface address as the default gateway.
