Configure the en1 interface

Depending on the number of interfaces you use for data, the en1 interface is used for inbound traffic or for both inbound and outbound traffic. The IP address you configure for the en1 interface is the IP address of the DNS Forwarder and HTTP Forwarder.

Make sure the IP address that you configure for the en1 interface is reachable.

By default, the en1 interface is configured to use the DHCP. As a result, these settings may already be configured. You can configure a static configuration. If you select a static configuration, make sure that you provide a valid IPv4 address. Currently, the security connector does not support IPv6.

As a best practice, if you are setting up a DNS forwarder, make sure that you use a static configuration for the en1 interface. For HTTP Forwarder, consider a static IP address. If you use a dynamic IP address, you should use a sticky MAC address assignment.

To configure the en1 interface:

1. If you are on the security connector main menu, press 2 or use the arrow keys on your keyboard to select Configure Networking and then press Enter. If you are on the Networking menu, go to step 2.

2. In the Networking menu, press 2 or use the arrow keys to select Configure en1 Interface and then press Enter.

3. Press E to edit the existing settings of the en1 interface.

4. To use a static network configuration:

   1. For the Data IP Mode, enter S, and press Enter.

   2. For the Data IP Address, enter an IP address, and press Enter.

   3. For the Data Subnet Mask, enter a subnet mask address, and press Enter.

   4. For the Data Gateway IP, enter an IP address, and press Enter.

5. To use a DHCP network configuration, enter D in the prompt for the Data IP Mode, and press Enter.

6. Enter y and press Enter to confirm that you want to apply the changes.

7. After the changes are applied, press Enter to return to the networking menu.
