That’s the problem, We’re receiving a ddos attack and i wanted to filter them on kernel level like in linux, or block the list of ip addresses which is ddosing us.

Also, i was trying to add multiple ips in a single rule in firewall, it only allows me to add one (or a range) i have a list of 8500 Ip addresses which i want to block using kernel filtering. Thanks.

If firewall cant do high level filtering, do you provide any app which allows it?
I want only specified udp packets which match the rules to be allowed through kernel and block all other trash packets.

I wanted to ask if we can create rules for udp like accept only packets containing a string lets say for example it contains string hi and i want to allow only it while blocking the rest and/or hex byte 2e on byte 30 or using u32 Binary for example 28=0xffffffff – which will block all packets containing /xff/xff/xff/xff after byte 28

Also, If its possible to add alot of ips in a single rule in it to block packets from those ips.
