I've searched many previous topics on this but i still have difficulty understanding
Can somebody share typical examples on where we should apply rules?
It DOES seem that WAN_LOCAL is where we should open our ports, and port forwards.
In my case, I have eth0 (wan port) with eth0.10 (vlan) and pppoe0 off eth0.10.
If I were to guess, portforwards and all the typical SOHO port stuff should be applied onto WAN_LOCAL which is off ethernet device pppoe0/local
so now im left with eth0/in eth0.10/in and pppoe0/in and im not very sure what rules to have for these.
