is it possible in iptables to forward a port, range of ports or all ports (ideally all ports) to all addresses on a subnet (rather than select an ip address at random from the subnet as would be done with the "-to-destination 192.168.0.2 192.168.0.254" switch)? Thanks for your help James -- On 5/17/6, a spammer known as PharmaMaster (PM) attacked Blue Security (BS). Using a program called Blue Frog, BS created a distributed network of over ½ mil users who would automatically send opt out requests to spammers' clients. This was so effective that PM declared that BS "found the right solution to stop spam, and I can't let this continue." PM then DDoSd BS, endangered the net by hacking a major router on the net's backbone to block BS' webpage and finally attacked typepad, where BS had just surrendered 30 min earlier. This attack caused about 2000 servers to go down including typepad and livejournal.While BS gave up because they felt this would "prevent a full-scale cyber-war that we just don't have the authority to start" The community disagreed and started a Blue Frog clone called okopipi which will prevents DDOS attacks by using decentralization. With your help we can fight back against PM and his spam mafia. Please join at okopipi.org and help take back our internet.
