Hi List,
I have previously used FWBuilder to build a firewall script, however now
I need a simple fw script to protect a single host that will not be
behind a net or anything like that...
Can someone point me in the direction of some easy scripts to reference
or some material good for a n00b to get me started ?
Thanks in advance
Continue using fwbuilder, to learn more compare the output of the
compiled firewall (it is a bash script) to what you do in the program.
The homepage for iptables/netfilter is
http://www.netfilter.org/
docs (with translations)
http://www.it.netfilter.org/documentation/index.html
generally if you don't serve something to the network simply:
- block connection that are not started from your host
- block malformed packets
- and accept the outgoing, one excepition is active ftp, on port 20.
ciao
francesco
