The limit on the number of MAC addresses is set separately for each server’s network interface. If you need more MAC addresses, create a request to support specifying the servers for which you need to increase the limit.

To increase this amount, you can use a package with daily billing:

Billing for increased bandwidth.

Bandwidth between Baremetal and VPCBandwidth between Baremetal and VPC

You can set up a connection between BareMetal and Virtual Private Cloud within the same region.

This connection has a default bandwidth limit of 10 Gbps for each user, regardless of the number of servers and their network card types. To request for a higher bandwidth, contact support.

The service is subject to the following broadcast traffic limits:

Blocked network portsBlocked network ports

The routers connecting BareMetal servers to the internet limit the incoming internet traffic to public server addresses on some TCP and UDP ports as well as the outgoing SMTP traffic. By blocking these ports you can protect the Yandex BareMetal infrastructure against malicious networking traffic.
