#### Network interfaces

Unlike SafeUTM, only a local Ethernet interface is created in Safe Center. To do this, click **Add**, select a network card, and fill in the required fields:

- **Interface name** - Name to identify the interface;
- **Network card** - Network adapter that will be used to connect to the Internet provider;
- **VLAN tag** - VLAN ID. Such a network interface is considered a VLAN interface. Filled in if the network card is already in use;
- **Automatic configuration via DHCP** - Use if your ISP supports automatic configuration of the Ethernet interface via DHCP;
- **IP Address/Mask** - Assign multiple IP addresses to an interface if required. At least one IP address is required;
- **Gateway** - IP address of the gateway;
- **DNS** - Two fields are available to specify the DNS server (optional).

#### Routing

Routing works similarly to SafeUTM routing. Detailed description at the [link](https://docs.safedns.com/books/45-setup-services/page/routing).

#### DNS

The principle of operation of DNS in Safe Center is similar to the principle of operation of [External DNS servers](https://docs.safedns.com/books/45-setup-services/page/dns) in SafeUTM. If the upstream router intercepts Safe Center DNS queries, then add external DNS servers.
