Seems like some sort of re-order in startup files would change that. Not sure if it is firewall later to dig under dhcp or firewall earlier so dhcp slips in behind it. Usually firewalls slip in right by the NIC, wrap the NIC and provide a virtual NIC, so they cannot be preempted. Talk to the firewall provider.

I have two items, only related because they are both regarding dhcpd.
First of all, I keep seeing dhcpd responding to DHCPREQUESTs on eth1 which is my cable modem. For example:

Hi there,
I setup a dhcp server on a debian.
It is designed to only assign ip addresses to a list of known hosts.
The config file looks like :

firewalld.conf
FIREWALLD.CONF(5) firewalld.conf FIREWALLD.CONF(5)
NAME
firewalld.conf - firewalld configuration file
SYNOPSIS
/etc/firewalld/firewalld.conf
DESCRIPTION
firewalld.conf is loaded by firewalld during the initialization process. The file contains the basic configuration options for firewalld.
OPTIONS
These are the options that can be set in the config file:
DefaultZone
This sets the default zone for connections or interfaces if the zone is not selected or specified by NetworkManager, initscripts or
command line tool. The default zone is public.
MinimalMark
For some firewall settings several rules are needed in different tables to be able to handle packets in the correct way. To achieve
that these packets are marked using the MARK target iptables(8) and ip6tables(8). With the MinimalMark option a block of marks can be
reserved for private use; only marks over this value are used. The default MinimalMark value is 100.
CleanupOnExit
If firewalld stops, it cleans up all firewall rules. Setting this option to no or false leaves the current firewall rules untouched.
The default value is yes or true.
Lockdown
If this option is enabled, firewall changes with the D-Bus interface will be limited to applications that are listed in the lockdown
whitelist (see firewalld.lockdownwhitelist(5)). The default value is no or false.
