Add, edit or delete Link Load Balancing pools

You can use Link Load Balancing pools in Source NAT & LLB rules to share traffic originating from IP addresses across multiple interfaces, increasing your available bandwidth in Smoothwall On-Premise Appliance.

Before you begin

Go to Network > Configuration > Interfaces and ensure the Bandwidth fields are set to the expected bandwidth of the upstream connection. For example, if you have a 1000 Mbps internet connection, but use 10,000 Mbps networks, set the value to ‘1000’ to indicate the expected bandwidth of the internet link is 1000 Mbps.

Add a new pool

1. Go to Network > Configuration > Link Load Balancing.
2. Select Add new LLB pool.
3. Enter a Name.
4. For Target bandwidth select:
   • Use maximum bandwidth: Use the maximum available bandwidth for this pool, so traffic is load-balanced across the connections added to the pool.
   • User defined: Define the minimum bandwidth needed. For example, if you have two connections of 100 Mbps and 50 Mbps, enter a minimum of 100 Mbps.
5. If you selected User defined, add the minimum bandwidth in kbps or Mbps. 
6. (Optional) Enter a comment.
7. Select Add.
