AWN201 Sensor Internal Tap Deployment

Deploy an AWN201 Sensor with internal tap Direct link to this section

The AWN201 Sensor is an external network device that allows you to monitor network traffic. When the sensor is deployed with internal tap, the sensor passively captures all network traffic between the switch and the firewall.

This image provides a simplified network map of a sensor with internal tap deployment:

Before you begin Direct link to this section

• Verify that you received the following items from Arctic Wolf:

  • AWN201 Sensor

    Note: Your sensor has a tamper-evident asset ID: AWN-12XXXXXX. Contact security@arcticwolf.com if the asset ID is missing or was tampered with.

  • Three CAT6 RJ45 Ethernet cables, 2m

  • Crossover RJ45 Ethernet cable (red), 2m — Use only if needed

  • AC30 US Power cord, 2m

  • Set of rack ears — Use only if needed

• For best performance, do not rate-limit the sensor with Quality of Service (QoS).

• If your firewall does SSL/TLS inspection, AllowList the sensor management IP address, and then check that your firewall allows outbound access from that IP address over port 443 to the necessary IP addresses.

  To see the complete list of IP addresses that you must allowlist, go to the Arctic Wolf Portal, and then click Account > Arctic Wolf IP Addresses. The IP addresses that must be allowlisted are listed under If you are a Managed Detection and Response (MDR) customer.

Steps Direct link to this section

1. Set up a customer-configured appliance.
2. Install the hardware.
3. Connect the sensor for internal tap deployment.

Step 1: Set up a customer-configured appliance Direct link to this section

See Set up a customer-configured appliance for additional information.

Step 2: Install the hardware Direct link to this section

1. Install the sensor in the applicable rack location.

   If necessary, use the provided rack ears.

2. Using a CAT6 RJ45 Ethernet cable, connect the management port (port 7) on the sensor to the outbound connection on your network switch.

3. Using the AC30 US power cord, connect the power connector on the sensor to a power source.

4. Turn on the sensor power.

   The Power LED is green when the sensor power is on.

5. Ping the management IP address that you provided to Arctic Wolf to check network connectivity.

6. Wait 15 minutes, and then make sure the Status LED is green. This shows that the sensor is connected to the Arctic Wolf monitoring service.

7. If you cannot successfully complete these steps, email security@arcticwolf.com.

Step 3: Connect the sensor for internal tap deployment Direct link to this section

1. Create a 1G internal tap bridge with ports 0 and 1:

   1. Using a CAT6 RJ45 Ethernet cable, connect port 0 (WAN0) on the sensor to the inside interface of your firewall.
   2. Using a CAT6 RJ45 Ethernet cable, connect port 1 (LAN0) on the sensor to your network switch.

2. (Optional) If you need to bridge additional internal interfaces to your firewall, create additional 1G internal tap bridges. Repeat the previous step with any of the following port pairs:

   • Ports 2 (WAN1) and 3 (LAN1)
   • Ports 4 (WAN2) and 5 (LAN2)

3. (Optional) Create a 1G mirror port connection:

   1. Configure a mirror port on your network switch.

      See the setup instructions provided by your network switch manufacturer for more information:

      • Cisco Catalyst 4500 Series switch
      • Cisco Meraki MS switch
      • Dell Networking Force10 switch
      • Juniper EX Series switch
      • Hewlett Packard Enterprise (HPE) ProCurve switch

   2. Using a CAT6 RJ45 Ethernet cable, connect port 6 (LAN3) on the sensor to the mirror port on your network switch.

4. Wait one minute, and then make sure network connectivity for network devices is not affected.

   Note: If network connectivity is affected, disconnect the sensor from the network, and then email security@arcticwolf.com to schedule a troubleshooting session.

5. Email security@arcticwolf.com to confirm that Arctic Wolf is seeing your network traffic.
