I've been configuring multiple firewalls that need to be identical recently and I got curious.
What is the purpose of abstracting OS interfaces to OPNsense's 'optN' interfaces, vs. using the OS names directly?
Thanks.
The OS names change when the hardware does.
Switch from 1G to 10G by adding a new 10G NIC? Simply reassign the logical interface to the new device - done. IP configuration, DHCP, firewall rules, NAT, ... all will just follow with a single click.
