hi slugs,
as i've spent days mucking around with ipchains and still seem to muck
things up.
i thought i'd ask a few questions to clarify my ideas on ipchains and
how it should best be set up in a particular situation.
is the following a good way to think about the ipchains rules?
define a new chain name.
ipchains -N dmz-bad
define the new chain route/direction of packets.
ie. if going from ip - from interface - to ip - jumpto dmz-bad.
ipchains -A input -s 1.2.3.4 -i eth0 -d 5.6.7.8 -j dmz-bad
define the rules for the ports in dmz-bad
ipchains -A dmz-bad -p tcp --sport 80 --dport 80 -j ACCEPT
does this make sense or is there a hole somewhere? disregarding the
default rules of course.
