I am looking for an opensource FW tool that I can blacklist all apps on my kids' devices, and just whitelist the ones, like an email client, podcast player, ebook reader subscription, and it looks like NetGuard will do almost everything I am looking for.
Two questions. 1. I don's see an option to set a password for the NetGuard utility so only the password holder (parent in this case) can access the app on the given device. Is this an option I am just overlooking (I hope)? 2. There are a couple of apps I want to be able to access servers on the local subnet but not access anything outside of the gateway router (internet). There does seem to be an option under SETTINGS > NETWORK OPTIONS where there is a greyed out ALLOW LAN ACCESS option setup. Will this option allow a specified app on the device to access resources on the local LAN, like a book or media server, but still block outside access?
I realized the grey-out feature likely requires a donation to unlock it, and I am just about on-board with donating if I can just get these two questions answered. Thks.
