I am moving from an old Dell Pentium D white box running software version 9.203-3 to a Dell Poweredge 1950 with 2 NICs (1GB). My current old Dell system originally had a built in 1GB Nic and a 2nd PCI broadcom 1GB Nic. I installed a new Intel dual GB Nic card based on the many threads mentioning better performance. My Nics are eth0,eth1, eth2 & eth3. Eth2 & 3 are the new Intel dual GB Nic card. Under my current UTM I removed the Eth1 Nic and disabled the Eth0 built in card as well as removed the Nics from Interface menu. I saw many threads stating you could not migrate to a system with less Nic cards. I made a backup of my config as it stands now.
On the new Dell PowerEdge 1950 I installed a clean copy of 9.201-25.1. I then walked through the initial setup and performed a firmware update to 9.203-3. I currently have no problem accessing the UTM on the Poweredge. My Problem is when I restore my backup, I loose access to the Poweredge. When I access the Poweredge locally from root, I run ifconfig -a and I see the NICs but they have no IP address assigned any longer. I have tried to manually assign the IP addresses, but after a restart they are gone again.
Is it possible because my old system sees the Nics as Eth2 & Eth 3 while the new install sees my NICs as Eth0 & Eth1 it is getting corrupted?
I have gone into the Poweredge and renamed the NICs as Eth2 & Eth3 in the /etc/udev/rules.d/70-persistent-net.rules file, but that has not helped.
I don't want to have to manually recreate all of my Network and Service descriptions and Firewall rules.
