I wasn’t intending to do any special configuration. My goal is to just have my NethServer as a standalone server sitting on a VPS. I pretty much just went through the basic setup, and probably accidentally changed some things I should not have changed.
I just read that document page, and it makes me think there is potentially a pretty big security issue then. The green network is currently showing my WAN IP, other than this I only have a disabled blue network.
If I understand correctly, the risk shouldn’t be too big, that WAN is considered “green”, because my NethServer isn’t acting as a firewall or handling networks for any other servers.
However, it seems that it would be best to add a Green interface with a static local IP (like 127.0.0.1 ?) and then change the existing Green interface with my WAN IP to a Red interface. Am I understanding correctly, or will this totally break my server?
