My questions are:
1.) What is a recommended "SYN PROXY SERVER" to filter bogus SYN Attacks and only forward "handshaked" valid connections to the host behind it (to be protected). I search the term, but did not find any direct hits/products,preferably open source/free?
2.) If there are not "ready built" Syn Proxy Servers, how can I build my own (with iptables?)
3.) Are Syn Proxy Servers recommended and usefull? Does anyone have any experience with it? (I otherwise might youse syncookies...)
Thanks very much! Markus
