From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A VLAN is not a security feature. Be sure that your firewalls and routers are configured properly and kept up to date.
Yeah, this is an important point tbh. Vlans alone don't add any security if your firewall doesn't do something to prevent it, as your router will happily forward packets to the next vlan. It should be on a DMZ vlan, meaning traffic is allowed in at the firewall but not to any other internal vlans.
If you allow it. Good routers should block forwarding by default, other than VLAN1 to WAN.
Yeah, I meant: isolated vlan
