DHCP Scope at setup
At initial setup, 192.168.100.1 was used for the LAN IP and a DHCP scope of 192.168.100.0/24 appeared in the interface, but all addresses being handed out were 192.168.1.0/24 with gateway of 192.168.1.1. A restart of the DHCP service did not correct the problem. Issue was corrected once the entire server was restarted. Systems which already had an IP on the correct network were able to access the Internet.
