Hi,

First of all this firewall script is the best I've seen. It has many
options and I got it working in less than 15minutes.

I have ADSL and NAT to many hosts on internal net. My ip_conntrack seems
to get filled with these:

udp      17 13 src=192.168.1.123 dst=192.168.1.255 sport=138 dport=138
packets=3 bytes=606 [UNREPLIED] src=192.168.1.255 dst=192.168.1.123
sport=138 dport=138 packets=0 bytes=0 mark=0 use=1

is there a way to keep ip_conntrack "clean" of these by preventing hosts
to broadcast these udp messages ?
