Configure L2 connectivity

Last update:

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 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 an A data center.

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

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 FortiGate port is allocated free of charge.

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

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

  1. В control panels create ticket with a request to organize a private network between devices. Specify:
    • identifier a dedicated server;
    • The FortiGate firewall number of the FortiGate firewall in the A data center. The number is listed on the unit card in the control panels 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 the 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 the section 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 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 configuring the FortiGate.
  2. Set the FortiGate interface address as the default gateway.
