FILTER 
BACKENDS(7)					 Miscellaneous Information Manual					FILTER BACKENDS(7)

NAME

       filter_backends - output drivers for the filtergen packet filter compiler

INTRODUCTION

       This document describes the status and feature-set of the currently available filtergen backends.

IPTABLES

       Most  development  is  done first against the iptables driver.  It supports reject, masquerading, transparent proxying, logging (with text)
       and sub-groups, all of which should work fine (though the latter has only recently been fixed).

IPCHAINS

       The ipchains driver supports all of the above features, too.  Its state model is much weaker though, of	course.   The  forwarding  support
       should work OK, though it is not possible to support "local"-only packets.

IPFILTER

       The  ipfilter  backend  is incomplete.  It supports accept, drop, reject and logging, but not masq, transproxy or sub-groups.  It should be
       easy for someone with knowledge of ipfilter to add support for the other features.  Options for OpenBSD "pf" features and syntax  would	be
       nice, too.  It has received no testing; I don't even know if the generated filters are syntactically correct.

CISCO

       The  cisco  driver is in roughly the same sort of state as the ipfilter one.  Additionally, because of the limitations of IOS ACLs, it sup-
       ports only a limited set of features.  It cannot support reject or transparent proxying, and  may  not  be  able  to  support  masquerading
       either.	An option for reflexive (stateful) ACLs would be very useful.

       I understand that Cisco PIX firewalls use a variant of this syntax -- it would be very nice to support them too.
