iperf Package testing of non-default gateways
- 
 I manage a pfSense box with multiple gateways. The default gateway is on our campus network but a second interface has a gateway to a cable modem. A recent event has led to a desire for us to be able to test the throughput of the cable modem. I downloaded the iperf package and am able to use the client portion to test bandwidth but it's testing the default gateway. Is there a way to set the source address used for the iperf client such as in the ping diagnostics tool? Thank you for any help.

 @lnguyen Thank you for the reply. Where in the UI would I enter the "-B address" switch?

 @ben_p You should be running it from a command prompt.

 @ben_p In the UI, Diagnostics Menu | Command Prompt | Execute Shell Command
