apalrds adventures | All About SUBNETTING your Networks! IPv6, IPv4, and VLAN Numbering Guide and OPNsense Demo @apalrdsadventures | Uploaded December 2023 | Updated October 2024, 5 hours ago.
You've probably heard all about creating multiple VLANs, for things like your IoT network, guest wifi, and more. But do you know what a VLAN actually is, and what the difference is between a VLAN and a Subnet? Today I'm going to cover the numbering of subnets in your network, and how to set up new subnet and VLAN interfaces in OPNsense. Come along on this adventure!
