Hello,

Is anyone aware of such firewall in linux. I have used ipcop,
iptables, shorewall and have read that applying netfilter patch to
kernel for HEX search can provide such capability.

 If you want to filter HTTP or HTTPS you can try apache's 
mod-security module (http://www.mod-security.org/)

 For protocls such as edonkey or ftp have look at l7 Filter 
(http://l7-filter.sourceforge.net). They says it works at 7th Layer. 
So you may be able to filter all well known protocols. I haven't 
tried it. So, feedbacks are welcome !
