Hello. Pietro Carvalho
To perform the speed test by a different interface from the default in Blockbit NGFW, you can use the following command: speedtest --source <IP_da_interface>
For example, to test through the IP interface 192.168.1.1, the command would be: speedtest --source 192.168.1.1
This command forces Speedtest to use the interface associated with the specified IP, allowing you to evaluate the performance of other links configured in the firewall.
