I currently use both SQM and an OpenVPN client on a 19.07.2 install of OpenWRT.
Should I use pppoe-wan or tun0? Any pros or cons maybe?
What per packet overhead should I add?
All my devices use the VPN client, with no exception.
Otherwise my network interfaces set up is pretty standard with a lan and a wan.
I have a VDSL2 broadband line (80,20) with Vodafone UK (soon moving to EE)
Let me know what other information you would need.
I am adding my current /etc/config/sqm
