Moving from PCI to PCIe NICs
-
I've picked up some PCIe NICs to replace the PCI ones that my box currently uses. I plan on keeping the PCI NICs in the box and moving my high traffic segments over to the PCIe NICs.
Can I just open the case and add the new cards? Will that screw up my current rules? If not, is there an easy way to then more existing rules/behavior to a new interface?
Thanks.

The additional NICs will be ignored by pfSense UNTIL you add them, configure and enable them. However if any of of the NEW NICs have the same device driver as existing NICs then you MIGHT find some of the existing NICs get renumbered.
For example, suppose you have some Intel PCI "em" NICs named em0 through em2 and you add two Intel PCIe "em" NICs, you MIGHT find the new NICs are numbered em0 and em1 and your existing NICs get renumbered to em2 through em4.

That's what I'm afraid of. They're all Intel NICs. Wasn't udev(I think) supposed to fix this issue?

So apparently my additional nics just got incremental em names. All of my existing rules, etc stayed the same.
