Individual users or (more commonly) a network subnet, are added to a user group at device level (within the Peplink router’s webGUI) and QOS may be applied individually to each group. The are three User Groups available : Manager, Staff and Guest. The Manager group always has unlimited bandwidth available, Staff and Guest bandwidth may be set to your preference. Once all subnets on your LAN are assigned to one of the three groups, we can apply both bandwidth limits and application based QOS to each group as needed, this is discussed below.
In the Peplink device’s interface, navigate to Advanced> QoS>User groups
Add the subnet to the user Group
Here we link the subnet 192.168.10.1/24 to the User Group “Staff”. The subnet should already be created in Network>LANS. Multiple networks, or single IP addresses may be added to the ‘Staff’ group if required. Note that the new QOS Client Group is at the top of list, this means it takes precedence over the lower ‘Everyone=Manager’, and the subnet you just created is in the group “Staff”, not “Manager”.
Set the bandwidth limit for each User Group
In the above example we assign 3mbps up and 3mbps down to the ‘Staff Group’, and tick to enable the bandwidth limit for the group. It’s important to note that download limits are set to 3mbps irrespective of how many WAN connections are established, so if the device has 1,2,3 or 4 WAN connections established, the user in the ‘Staff’ group would still get 3mbps download. The upload limit is per established WAN, so in the example above, if two WANs are established the user would actually be allowed 6mbps upload.
Set the application priority for each User Group
If required, certain traffic types may be prioritised to certain groups. Here, we give any network client in the ‘Manager’ group higher priority with streaming applications.
Other QOS Settings
DSL/Cable Optimization : this should be enabled of your WAN upload and download speeds are different by a factor of 3 times or more (asymmetric). For example with a fibre WAN 50/50mbps it should not be used but with a VSAT 15/2.5mbps this may improve performance, because with this feature enabled the download speed is less affected by a saturated upload link.
PepVPN Traffic Optimization : Enable this option to allow PepVPN traffic has highest priority when the WAN is congested with both VPN and non VPN traffic.
