iptables firewall
I'm trying to set up a proper firewall, and have a decent one set up so
far..
A few things I'm missing though are the ability to allow/deny ipranges,
so I have been looking around a bit, and saw that there was a module
called iprange.
How do I install this with debian? Doesn't seem like there is an option
to enable it when building a kernel, nor any deb package with it, and to
be honest I'm quite a linux illiterate when it comes to patching
something like iptables :(
Another thing with iptables I have been thinking of letting my firewall
do, is to give a proper reply to connections on closed ports, rather
than just dropping the connection.
Reason for this is that I run a few services for LAN only that I cannot
simply bind to the LAN side. Also when people know my host is up and
tries to connect to a specific port, rather than having to time out
their client would just get the standard (its even in som RC if I
remember correct) "closed" reply.
Hope someone is able to help on this one..
Sincerely
Brian Schmidt
