Hi Dennis,

I Miss a rule like

ACCEPT   udp  --  anywhere             anywhere            udp dpt:dhcp

in your setup

dhcp-requests uses the udp-protokol and the port 67

See the following output on my fli4l-router-machine (dnsmasq is
configured as dns and dhcp-server)

netstat -nap | grep dnsmasq
tcp        0      0 0.0.0.0:53              0.0.0.0:*
LISTEN      3510/dnsmasq
udp        0      0 0.0.0.0:53              0.0.0.0:*
        3510/dnsmasq
udp        0      0 0.0.0.0:67              0.0.0.0:*
        3510/dnsmasq


Cheers,

Peter
