udp 1900 is open while INPUT policy is set to drop or reject.
Probably a bug in iptables or so as UPNP port 1900 is open while the policy is set to drop or reject everything whitot a rule. this a problem as you use lmce as router and direct al traffic to it (DMZ HOST). So i set our standard firewall to drop port udp 1900 from EXTIF.
