@JarekPrzybyl try upgrading your router, you have a very old version and a lot has been fixed

@LeoFialho yes why not? wireguard and openvpn work well that way

@olli_foxtech go to global and controller settings

@vahur All Omada routers can be used stand alone, so you don't need a controller. Recommend ER8411

@BennyNissen 1. remove all manual routing. you should not route anything

@FokkoBrugge yes, you need to install java 17 sudo apt install openjdk-17-jdk-headless To manage the active version, don't forget about the update-alternatives command: sudo update-alternatives...
