is it possible in openwrt to prioritize the traffic of one client ?
I have my work-laptop that is making a VPN-connection to my company. Via this, I also make VoIP- and Videocalls. If, for example, I make a download on an other client the VoIP-calls are almost impossible to make. So, I want to prioritize the traffic of the laptop's IP. Is there a chance ?
setup cake and layer_cake
Use custom firewall rules to set desired DSCP marks. There are more threads about this but this one shows info on how to check if everything is working properly: Checking DSCP tags
Start by installing luci-app-sqm and enabling the simplest SQM config (piece_of_cake.qos) with sensible bandwidth settings. This will probably be enough to solve your problems, without having to get down and dirty with layer_cake.qos and DSCP tagging.
