Traffic shaping

In these examples we assume that the WAN port of the firewall is connected to Internet with an up and downstream bandwidth of 2 mbps.

Limit bandwidth to a service

To limit bandwidth a service (in this case FTP) can use, follow these steps:

1.Create a new policy rule. Under Firewall->Policyclick LAN->WAN. Click Add new.

2.Setup he new policy

Name the rule allow_ftp

Set position to 2

Set action to allow

Select service: ftp_outbound

Schedule should be always

Check the Traffic shaping box and enter 400 as up and downstream limit.

Click Apply

3.Click Activate and wait for the firewall to restart.

All FTP traffic from computers on the LAN network will now be limited to the total bandwidth of 400kbit/s in both directions.

Limit bandwidth to one or more IP addresses

The example above can be modified to only limit FTP bandwidth from one or more IP addresses. In the policy setup, add the IP addresses that should be limited in the Source Nets box.
