Change Order of Interfaces on VM

(1/3) > >>

Hello all, I have a pfSense 2.2.1 VM running on ESXi 5.5 U2 that I'm trying to rebuild because it won't vMotion or svMotion when it's turned on. It currently has 2 E1000 and 4 VMXNET3 adapters because it gave issues when I tried to run all six as paravirtualized.

When I start a new VM, even before I install pfSense, the order of the NICs changes if I add more than 4 VMXNET3 adapters. In Linux I could simply go to /etc/udev/rules.d/70-persistent-net.rules and change it to how it's supposed to be, and all of my FreeBSD searching points me towards a /etc/rc.conf or /etc/rc.local file that doesn't exist in pfSense. I've tested with 2.2.1 and 2.2.2, and I'll revisit today with the new 2.2.3 release.

Is there a way I can manually re-order the interfaces in pfSense?

what does it matter what order they are seen in pfsense?  Are you saying they change on reboot?

I just make sure I know what the macs are in esxi, and then assign them in pfsense on what they are connected to in esxi. 

I started with 3 and then 4 NICs and they are in the correct order, but when I add a 5th it changes the order of them to something like 1-5-4-2-3 and it re-orders them again when I add a 6th. Changing the port-groups does fix it, but will I need to change it all again if I ever need a 7th? Plus I have VLAN interfaces that all need to be changed to bind to a different interface, so it becomes a slightly confusing and very time consuming process. I'd rather just change how the OS sees them so I can keep the same config.

I haven't done enough testing to see if it's a random order, but if it is that would also create a problem since I'm trying to setup a second firewall and sync the two.

Also, the order is persistent through reboot, but does change if I add another NIC.

It is a pain. Especially when management nic is not on vmnic0. I just note the mac address of my nics and the vSwitch that they are assigned to before shutdown and configure network as needed.
