The first step in speed limitation is to create a group with a range of addresses for which we will limit browsing speed. This is done in User -> User -> root -> +Add User (IP Range).

​

Once the User with the address range is created, go to Flow -> Flow Control Policy, and enable Flow Control on the WAN interfaces as follows:

With the changes saved, tabs are enabled at the top. Go to Change Policy, and add a new policy.

Name the policy, select the created User, and set the speed limit, in this case, 10Mbps.

After saving the changes, proceed to perform a speed test to verify if the applied changes have taken effect.
