Dedicated server networks
Dedicated servers are connected to Selectel's network infrastructure by default and can be connected to:
- to a public network (internet);
- a private network (local area network).
Some Chipcore Line servers are connected only to a public network; you cannot connect them to a local area network.
To connect a server to both a public and a private network, use separate network interfaces (aggregated network interface group):
- internet port;
- port for local network.
You can view information about server ports in the Control Panel: in the top menu, click Products → Dedicated Servers → Servers → server page → tab Ports.
The server is automatically included in the shared VLAN for the public network, and is allocated one IPv4 public address from a shared subnet.
If only one dedicated server is ordered for an account, a VLAN for a private network is not allocated. A VLAN for a private network is automatically allocated when ordering the second and subsequent dedicated servers for an account. One VLAN for a private network is allocated per account in one pool. If you need a VLAN for a private network, for example, to set up connectivity with a firewall or a cloud server, create a ticket.
You can view a list of all VLANs in the Control Panel: in the top menu, click Products → Dedicated Servers → Network → tab VLAN.
To connect to a network, you may need to configure network interfaces on the server.

If a dedicated server is unreachable over the network, you can connect to it via the KVM console. For Chipcore Line servers, you can order the additional service IP-KVM access for 3 hours or boot into recovery and diagnostics mode.
Connection to a third-party operator
Many telecom operators have a point of presence in Selectel data centers. You can organize a direct connection to them using the Direct Connect service:
- Direct Connect — physical port — leasing a port on a Selectel access switch. In this case, you organize the connection from the telecom operator's side yourself (verifying connectivity to Selectel, checking cross-connects, paying for communication channels, etc.);
- Direct Connect — logical port — lease of a pre-established, reserved connection between Selectel and a partner backbone operator.
Blocked ports
To protect the Selectel infrastructure from malicious network activity, certain TCP/UDP ports are blocked, including port 25 (e-mail mailings).
If a port is not subject to these restrictions, check its availability from the OS using the Nmap utility.
