ipfwadm-wrapper - IP firewall administration


SYNOPSIS

       ipfwadm-wrapper -A command parameters [options]
       ipfwadm-wrapper -I command parameters [options]
       ipfwadm-wrapper -O command parameters [options]
       ipfwadm-wrapper -F command parameters [options]
       ipfwadm-wrapper -M [ -l | -s ] [options]


DESCRIPTION

       Ipfwadm-wrapper emulates the behaviour of ipfwadm. You can
       use this wrapper to use your old  ipfwadm  firewall  rules
       with ipchains. See ipfwadm(8) for more details.

       If  the  kernel  does not support ipchains (eg. a 2.0 ker­
       nel), and the file /sbin/ipfwadm.real exists and  is  exe­
       cutable, then it will be executed with the arguments given
       to ipfwadm-wrapper.  This allows  simple  dual-booting  of
       2.2  and  2.0  kernels  with the same firewalling scripts:
       simply move ipfwadm to ipfwadm.real,  and  ipfwadm-wrapper
       to ipfwadm.

BUGS

       The script isn't clever at parsing command line arguments.
       You must use separate  arguments,  rather  than  run  them
       together.   For  example, `ipfwadm -Mle' becomes `ipfwadm-
       wrapper -M -l -e'.

       Fragment accounting rules are  not  translated  correctly;
       they will account packets with source port 65535.

       Due  to  new kernel restrictions, you must be root even to
       list rules for 2.2 kernels.

       If /usr is mounted from NFS, you will not be able  to  use
       ipfwadm-wrapper before /usr is mounted.
