Hi Heiko,

After working with devil-linux for a week or so I found
it arduous to keep
manually entering static routes / arp entries for my
DMZ interface.  I
checked the devil-linux cvs for any updates or
solutions and didn't see any
so here is a possible solution for your review.  I do
realize that many
people may just add the route / proxy additions to the
firewall.rules script
however this is less than ideal if you want to use
fwbuilder for your rules
generation.  Most installations static entries / proxy
arps won't change
while their firewall.rules will which made it more
desirable to place these
in another script.

This is a really simple addition.  I made it flexible
enough that you can
specify a begin and end address for say a whole class c
block to listen on
your external interface and proxy arp to the dmz
interface.  It requires two
additional scripts and a modification to the config
script to add the
variable ADD_STATIC_ROUTES right before the firewall
rules are loaded.

Summary
-----------
/etc/sysconfig/config - Addition of variable
ADD_STATIC_ROUTES

/etc/init.d/routes - New startup script
/etc/routes.conf - New configuration script

chown 700  /etc/init.d/routes
chown 700 /etc/routes.conf

Changes to runlevels
-------------------------
ln -s ../routes /etc/init.d/rc3.d/S06routes
ln -s ../routes /etc/init.d/rc5.d/S06routes

Attached find the three files in question


Additional Info which may or may not be helpful
----------------------------------------------------------

Here is my basic setup to get a picture

default gateway =  66.247.73.174

eth0 - external static "66.247.73.169" 255.255.255.248
eth1 - dmz bogus address "192.168.254.254"  public
range 170-173 are arped
via eth0 and a route entry
eth2 - internal "192.168.0.1"

Using fwbuilder for iptables generation

With this setup I only give up one static ip address
for the firewall ext
interface... many other references on the net show how
to create dmz's but
give up extra addresses because they use their public
addresses for the dmz
port.  The dmz bogus address is just that bogus, it
prevents the routing
table from seeing it as 0.0.0.0 and screwing things up
for your internal
interface.  Most isp's don't assign blocks large enough
these days to be
worth subnetting out so I find this works well and
preserves the address
space for those of us with small subnets.


Thanks,
Matt Axsom
