    Добавить еще один сетевой интерфейс это дело техники, ничего особенного делать не надо, поэтому какого-то конкретного совета я дать не могу. Могу предположить, что либо dnsmasq не обслуживает новый интерфейс, либо nat не настроен в iptables. Нужно аккуратно проверить все конфиги и правила iptables. Убедиться, что все везде корректно настроено, разрешено. К тому же не понятно, в чем конкретно проблема.

В принципе, добавить нечего, в файле даны все комментарии. Так что в обычной работе эти строки нужно закомментировать, и использовать только во время отладки.

    Mais j’en ai aucune idée de comment faire, et sur les autres forums, c’est très très mal expliqué donc je ne peux pas faire. Du coup je pense qu’il faudrait que daemon ait les droit root, ou bien aller dans les configurations de xamp (car c’est xamp mon webserver) pour daemon puisse faire du chmod.
