Bumblebee CPE Pass Through Mode

IP Address Allocation

Bumblebee Internet CPE supports a "Pass Through" mode where the CPE takes one IP address from the public subnet provided by the carrier and leaves the rest of the addresses to the customer network. All the visibility and monitoring capabilities are preserved.

The table below illustrates the IP addresses distribution for different subnet size allocations from the service provider.

Service Provider WAN subnet	Total IP addresses	Total Usable host addresses	Service Provider default gateway IP	Bumblebee CPE IP address	Customer Network addresses
/28	16	14	1	1	12
/29	8	6	1	1	4

As an example, say the service provider's subnet is 167.98.180.49/29. In this case, the usable host IP address is 6. After taking account of the service provider default gateway IP address 167.98.180.49 and the Bumblebee CPE IP address 167.98.180.50, the customer will have 4 usable public IP addresses.

Bumblebee CPE Pass Through Mode

Configurations

You can enable Pass Through mode either at CPE create time or later after it has been deployed.

Switch from Router Mode to Pass Through Mode

To switch from Router Mode to Pass Through Mode after it has been deployed, follow the instructions below.

1. Login to the Bumblebee platform portal

2. On the left navigation menu, click Intelligent Edge -> Internet CPE.

3. Select on CPE device from the list view, click Actions -> Edit Network Info

4. (Fill the Upload speed and Download speed if you have not done so. If these two fields are left unspecified, the default 1000Mbps are assumed)

5. Select Pass Through radio button. Proceed to the next step.

6. Unselect DHCP Client if the service provider side default gateway router only supports static IP configuration.

   1. For IP Address field, enter one IP address from the WAN network address pool in CIDR format. For example, 167.98.180.50/29, indicating this is a /29 subnet with 167.98.180.49/29 as the default gateway IP address.

   2. For Default Gateway field, enter the default gateway IP address allocated by the service provider. For example, 167.98.180.49

   3. For DNS Server IP(s) field, enter one or multiple DNS server IP address. For example, 8.8.8.8

7. Click Save

8. This triggers change. The CPE may or may not go down during this transition. When it comes back up again, the configuration is complete.

9. To verify the configuration is complete, check the CPE Details in the bottom half of the List view. You should see the configuration of the Management Interface

Specify Pass Through Mode at device creation time

To specify Pass Through Mode at the create time, click the Create Device and select Pass Pass Through. Follow the same steps outlined above to create a device in Pass Through Mode.

Eth2 as a LAN port

When a CPE is in Pass Through mode, the Ethernet port marked as Eth2 on the CPE can also be used as a LAN port. This provides a solution to the use case where a second Firewall or router device, for redundancy purpose, can be directly connected to the CPE.

Add VLAN Tagging

To deploy Bumblebee CPE for facilities-based service provider, VLANs are often used. To configure it,

• select the CPE once it is created,

• go to Actions -> Edit CPE Info

• Check Enable UNI NID

  • Check Enable VLAN tagging

    • Enter VLAN ID

  • (Optional) Check Enable VLAN Q-in-Q VLAN tagging

    • Enter Q-in-Q VLAN ID
