When do you use "Limit Uplink" configuring QoS? My gut tells me this would literally limit the bandwidth available for the interface, the but help guide makes it sound like something else just used to perform QoS calculations.
My setup is Verizon fiber into building to Verizon rack. I then connect the UTM to an Adtran router also provided by Verizon, providing a 50m up/down connection. Based on the instructions, would this mean I need to select this box? Or does router mean something more like a home DSL router and my configuration would actually be "Static connected directly to the internet"... meaning don't check the box.
I am just not sure which I technically am, connected directly to internet, or router sitting in between gateway and internet. I haven't even seen a situation where a UTM would be connected straight to the internet... doesn't there have to be a ISP provided router of some sort? Seems like a stupid question, not sure why I'm doubting myself. I swear someone advised me to uncheck the box at some point.
Thanks!
Jim

Limit Uplink: Selecting this option tells the QoS function to use the configured downlink and uplink bandwidth as the calculation base for prioritizing traffic that passes this interface. The Limit Uplink option is selected by default and should be used for the following interface types:
◦Ethernet Static interface (with a router sitting in between the gateway and the Internet—the bandwidth provided by the router is known)
◦Ethernet VLANCollapsed interface (with a router sitting in between the gateway and the Internet—the bandwidth provided by the router is known)
◦DSLCollapsed (PPPoE)
◦DSL (PPPoA)
◦Modem (PPP)
Clear the Limit Uplink checkbox for these interfaces whose traffic shaping calculation base can be determined by the maximum speed of the interface. However, this only applies to the following interface types:
◦Ethernet Static interface (directly connected to the Internet)
◦Ethernet VLAN interface (directly connected to the Internet)
◦Ethernet DHCPCollapsed
