Hi: Does there exist a standalone iptables implementation that does the packet filtering and that does not rely on the iptables sitting in Linux kernel. If I am not wrong then the iptables-standalone.c that is available at netfilter.org only provides the interface to specify filtering policies. I am looking for complete user-level implementation with minimal help from kernel.
