This installs pfSense as follows:

• Separate networks for:
  • LAN: Generic Local Network. Uses pfSense for DNS queries. Filters DNS for Spam, etc.
  • CLEAR: No SPAM filtering at all, etc. Uses external DNS. Backup to the internet just in case the filtering on the LAN network somehow prevents access to the internet.
  • IOT: For IOT devices. No access to other networks. Forces internal DNS and NTP to be used.
  • GUEST: For Guests. No access to other networks. Allows external DNS to be used by guests.
