2.4.4 on ESXi 6.7 - Add I/F, no I/F mismatch
On a new ESXi 6.7 install I created a new pfSense 2.4.4 VM, initially with WAN and LAN interfaces only. (WAN is not physically connected yet and doesn't get an IP.)
When I added a new DMZ port group and connected it to the VM I expected to get an "interface mismatch" message at boot and have to re-assign.
The mismatch didn't occur and the VM came up with both WAN and LAN recognized. When I went to assign interfaces in the console, the new interface (vmx2) was there and could be assigned.
No impact in this test environment but wanted to report in case it is unexpected behavior.
Why would you get a mismatch error for a new interface?
The only time a mismatch happens is if it can't find an interface that must be there. For example if you had DMZ assigned and then removed that extra interface from the VM without removing it from pfSense first, that would be a mismatch.
All you did was add a new interface, the ones pfSense cared about were still there. That's not an error state.
