Interfaces changes after reboot lead to DMZ unreachable

[saintjimmy]

Hello

After a reboot of my VM all the network interfaces names changes (igb2 became igb0 etc...). I reassigned the interface to the correct NIC and I have Internet access.
For a reason I can't figure my DMZ is now unreachable from the outside. NAT and FW hasn't changed though.

Thanks for your help
