How do I reset network interfaces

[LexiCodes]

I have been trying to setup pfSense but I accidentally set the pfSense vm to the integrated network controller on my server (one of the 4 ports on a dell r720).
I have already run (VM number is 104)
qm stop 104
qm destroy 104
Any help is appreciated!

Assuming that this is the only thing you did, deleting the VM with the two commands that you have executed should be enough to revert any changes.

Could you share your /etc/network/interfaces file? Also also give some more details on what's wrong and what the desired configuration should be?
