Hi,While investigating a streaming issue in my network, I was surprised to see a run of Speedtest showing my download speed at around 85Mbps, which is less than half the speed I am supposed to get from my ISP, 200Mbps. Running a few tests, it appears (on the surface) that Shorewall is throttling this down, because if I turn it off, then I get my advertised 200Mbps.
This is running on a Nethserver install connected directly to my cable modem. Nethserver is based on CentOS 6.7 and runs Shorewall 4.6.4.3. The Traffic Shaping option offered by Nethserver is disabled.
Here is the console log of my Speedtest runs, plus I have attached the output from "shorewall dump".
