I'm trying to setup QoS rules to achieve the following:

I want to restrict the bandwidth for specific IP addresses that connect to the network. I'm confused about what goes in each of the fields seen in the screenshot seen below when setting up the QoS rules. Anyone who has done it before and can help understand what to put in each of these fields?

  • Source IP
  • Dest IP
  • Source Netmask
  • Dest Netmask
  • Up Floor/Ceiling
  • Down Floor/Ceiling

    Me too... I don't know if it is wrong translated or if I don't know that dialect :)

    I'd once got it to work somehow by trial-and-error but then unfortunately reset my router and lost all the effort... now want to do it the proper way after understanding. :-)

    Almost everything I check online has a different interface or options with this feature... dlink.com/uk/en/support/faq/routers/mydlink-routers/dir-605l/… and for example...support.dlink.com/emulators/dir600/101NA/tools_firmw.html Maybe try updating firmware and then looking over the options again....

    @PIMP_JUICE_IT also updated the firmware thinking would get a different interface but the interface remained same. And actually that is when i lost the settings that worked by trial and error earlier. I should've backed em up. :(

Source IP : Where traffic from. If you set source IP with 192.168.0.1, traffics from 192.168.0.1 will be controlled.

Dest IP : Where traffic heads to. If you set dest IP with 192.168.0.1, traffics headed to 192.168.0.1 will be controlled.

Source Netmask : Determines range of source IP address. It's according to IPv4 CIDR subnetting rule.

Dest Netmask :Determines range of dest IP address. It's according to IPv4 CIDR subnetting rule.

Up/Down Floor : Floor is speed that you want to guarantee least. For example, if you set Up/Down Floor to 10Mbps, you can guarantee at least 10Mbps speed for upload and download.

Up/Down Ceiling : Ceiling is speed limit. For example, if you set Up/Down Ceiling to 10Mbps, your upload and download speed is limited to 10Mbps, and you cannot use any more than that.

== Example ==
Source IP : 192.168.0.5
Dest IP : 0.0.0.0
Source Netmask : 255.255.255.255
Dest Netmask : 0.0.0.0
Up Floor/Ceiling : Floor 0 Mbps, Ceiling 10Mbps
Down Floor/Ceiling : Floor 0 Mbps, Ceiling 10Mbps

    that was implied. can you explain with an example? what would the values be in the first 4 fields if i would want to limit the bandwidth for ip 192.168.0.5 ??

    Well, if you want to control traffic from 192.168.0.5 for maximum 10Mbps, it could be this :<br/><br/>Source IP : 192.168.0.5<br/> Dest IP : 0.0.0.0<br/> Source Netmask : 255.255.255.255<br/> Dest Netmask : 0.0.0.0<br/> Up Floor/Ceiling : Floor 0 Mbps, Ceiling 10Mbps<br/> Down Floor/Ceiling : Floor 0 Mbps, Ceiling 10Mbps,<br/><br/>This will limit traffic from 192.168.0.5 to 10Mbps max, and will not guarantee lowest speed. If you want to guarantee lowest speed, set Up/Down Floor with desired speed.

    Sorry for messy comment. This thing looks like doesn't support line break.
