Are Source "Nets" and "Subnets" the same thing?
-
I'm following the Netgate 2100 instructions for setting up an isolated/guest network bound to a specific port/interface on the device (https://docs.netgate.com/pfsense/en/latest/solutions/netgate-2100/opt-lan.html)
I've kept almost everything the same as was was outlined except that I named the interface
GUEST4(instead of OPT1), and am using the subnet192.168.100.1(instead of 192.168.2.1).Under the "Configuring the Firewall" section of the guide, there are instructions for adding firewall rules to the interface. The first one is to allow DNS traffic. The instructions and the screenshot at the end say to select "OPTx Net". In my case that would be "GUEST4 Net". However I don't see any option in the source drop down that corresponds to that. Among some others, there are options for "Network (manually enter IP), "GUEST4 address" and "GUEST4 subnets".
I'm assuming I want to use "GUEST4 subnets", and that such a rule would allow all devices connected to that interface to make DNS queries to the firewall. Perhaps the nomenclature was changed or updated, but not reflected in the guide?
Is there any practical difference between selecting "GUEST4 subnets" as the source and selecting Network then entering
192.168.100.1/24? -

Yes.
