HA Not Working due to Interface Number(s)

[Cornelp]

So,
I have 2 Firewalls (Primary and Backup). Each firewall has 10 interfaces (running under VMWare).
Firewall 1 has
WAN
LAN
Opt1
Opt2
Opt3
Opt4
Opt5
Opt6
Opt7
Opt9

Firewall 2 has
WAN
LAN
Opt1
Opt2
Opt3
Opt4
Opt5
Opt6
Opt7
Opt8

Somehow, Firewall 1 skipped Opt8 and went directly to Opt9. Due to the fact that Interfaces are NOT the same on both firewalls, they wont sync configs.

How can I get FW02 to be the same as FW01 when it comes to interface numbers?

Thanks,

Either delete opt9 on the primary and recreate it. It will be opt8.

Or create a new interface on the secondary, which will be opt9 and delete opt8.

1. If I delete Opt9, will that mess up the rest of the interfaces? As in, will PfSense pick up the interfaces now in a different order?
2. In VMWare you can only add 10 Network Interfaces, you are locked to 10. I already have 10 added. How can I go about that now?

Thanks,

It would probably be easier to take a backup of the primary, replace opt9 with opt8 in a copy of the backup, then restore the edited version.
