This rule

> -A INPUT -i eth0 -p udp -j udpincoming_packets

makes these two worthless

> -A udpincoming_packets -i eth1 -p udp -m udp --sport 67:68 -j ACCEPT
> -A udpincoming_packets -i eth1 -p udp -m udp --dport 67:68 -j ACCEPT

There's no way a packet can simultaneously match -i eth0 and -i eth1.
So no bootp.dhcp traffic is actually allowed by this.

Delete the sport rule and put the dport rule in the main INPUT chain,
no need to consider broadcast and unicast separately.
