I have a router set up just for my wifi cameras. The router is not plugged into the internet, but it is directly connected to one of two Ethernet ports on my ×86 home assistant server. The other Ethernet port for Home Assistant is connected to the internet. Is there any chance a device connected that router could somehow access the internet from homeassistant?
I have AdGuard Home connected to the isolated network (running on home assistant) so I can use the DHCP server and UI. Any chance AdGuard could be that sort of extra software you are talking about?
I’m not overly familiar with Adguard, but I would say no. Adguard provides an ad blocking DNS sever and DHCP server, but neither of those handle routing.
Thanks for the response. That’s a big relief.
