I am trying to set up sqm for my wan in default OpenWrt on a Linksys3200acm, it is bridged to a Asus-dsl rt86u modem. I have installed k-modveth, ipfull, and app-luci-sqm on OpenWrt.
Incoming WAN traffic will forward to veth0
Incoming WAN traffic to destination LAN will forward to veth0
I have attempted to set it up with the following:
add veth1 to br-lan bridge
sqm egress veth0, sqm ingress veth1
apply these rules
```
ip link add type veth
ip link set up veth0
ip link set up veth1
ip link set veth1 master br-lan
iptables -A FORWARD -i eth1.2 -o veth0 -j ACCEPT
iptables -A FORWARD -s -i eth1.2 -d br-lan -o veth0 -j ACCEPT
```
This is not functional. I need a step by step guide for setting up a veth pair for OpenWrt.
