Bumblebee CPE Router Mode

For Pass Through mode, refer to this article.

This document walks through a Router Mode design example for a scenario where site Firewall device wishes to use static IP address from a range provided by service provider.

When is a Router Mode implemented

If the service provider assigns a site a single subnet, such as a /29 subnet, the WAN design calls for Pass Through mode.

On the other hand, there are times when the service providers assigns a site two subnets, a /30 subnet and a /29 subnet. In such, use Router Mode for WAN design.

Note Bumblebee LAN interface (ETH1) is the default gateway for the /29 subnet.

Example configuration

Below is a example screenshot of the network configuration portion of creating a device.

In the example, the WAN (ETH0) subnet default gateway IP is 12.77.108.81, the DNS is 8.8.8.8. The Eth0 for CPE is 12.77.108.82/30.

On the LAN (ETH1) side, the Bumblebee CPE ETH1 is the default gateway, it is setup with IP address 207.140.129.193/29. The remaining usable IP addresses for customer's internal network are: 207.140.129.194, 207.140.129.195, 207.140.129.196, 207.140.129.197 and 207.140.129.198.
