The packets could come from 255.255.255.255 or multiple other addresses of the form 10.*.*.255. What kind of syntax do I use to DROP these packets? The line below will filter out packets from 255.255.255.255 but I'm not sure what syntax to use to DROP the other adresses. iptables -A INPUT -d 255.255.255.255 -p udp -j DROP Regards, GJ _________________________________________________________________ Worried about inbox overload?
