Should I be able to get an IP from the router without the WAN connected?

[AverageGuy]

I lost an Ethernet port on my F2B.  I had a spare so I downloaded the latest backup configuration to a thumb drive and started a fresh install of OPNSense on the new hardware.  I connected my laptop to the LAN port thinking I wanted to be sure it was working so I wouldn't PO my wife when the network stopped running.  The laptop is running Linux.  I've rebooted both systems a number of times but I can't seem to get the router to issue an address.  I checked the config and the lan is configured as igb0 with an IP address of 192.168.2.1 /24.  The range for DHCP is 192.168.2.100 - 192.168.2.201 and is enabled.  Something strange is that I find no mention of the wan nor of igb1 device.  The only entries in the xml file in the interfaces section are lan and lo0.  Same for the saved config from the original system.

Should I just start over from scratch.  I hate to do that since I have so many static IPs and other changes.

Thanks.

Check the configuration history on the original system for the last version which still had the WAN. Download this and restore it on the new hardware.
