This guide will walk you through the steps to load balance traffic across multiple instances of the Barracuda CloudGen WAF deployed in the old Microsoft Azure Management Portal.
To configure a load-balanced set in the old Microsoft Azure Management Portal, do the following:
Complete the steps in Step 1. Deploy the Barracuda Web Application Firewall Instances in Microsoft Azure and Step 2. Set Up a High Availability Environment With the Barracuda Web Application Firewall under the Configuring a Load-Balanced Set Using the Classic Model section, and proceed with the steps below:
Step 3. Set Up Load Balancing on the First Barracuda CloudGen WAF Instance
- Go to the Microsoft Azure Management Portal.
- Click Virtual Machines and select Barracuda-WAF1.
- Click ENDPOINTS, and then click ADD.
- In the Add an endpoint to a virtual machine window, select Add A STAND-ALONE ENDPOINT and click the arrow to continue.
- Specify values for the following fields:
- NAME – Enter the name for the endpoint. Example: HTTP
- PROTOCOL – Select TCP from the list.
- PUBLIC PORT – Enter the port number of the service you are load balancing. Example: Port 80 for HTTP traffic.
- PRIVATE PORT – Enter the internal port that should listen to traffic on the endpoint. Example: 80.
- Select Create A LOAD-BALANCED SET and click the arrow to continue.
- In the Configure the load-balanced set window, specify a name for the load-balanced set and assign the values for the load-balancing probe.
- Click the check mark to set up a load-balanced set.
- Repeat the process to add more ports to the load-balanced set.
Step 4. Add Other Barracuda CloudGen WAF Instances to the Load-Balanced Set
After you create the load-balanced set for Barracuda-WAF1, add other Barracuda CloudGen WAF virtual machines to the set. Example: Barracuda-WAF2
- Go to the Microsoft Azure Management Portal.
- Click Virtual Machines and select Barracuda-WAF2.
- Click ENDPOINTS, and then click ADD.
- In the ADD ENDPOINT window, select ADD AN ENDPOINT TO AN EXISTING LOAD-BALANCED SET and then select the load-balanced set name from the list. Click the arrow to continue.
- In the Specify the details of the endpoint window, specify a name for the load-balanced set and then click the check mark.
- Repeat the process to add more Barracuda CloudGen WAF virtual machines to the load-balanced set.
