I've mentioned this before, but you might also want to check out some example firewalling scripts which would probably enlighten you a bit more than just simply reading the iptables documentation. There are some good ones here:
http://www.linuxguruz.org/iptables Probably the one that I liked the most had lots of comments and was somewhat more organized than a lot of other scripts that I have looked at. That one can be found here: http://www.linuxguruz.org/iptables/scripts/rc.firewall_023.txt BTW, if you are running a simple in-house network where you aren't overly concerned about internal attacks, you could just allow all local TCP packets through your firewall. You probably will want to block all connections to X (port 6000) from the external world though. Something like this will allow everything on your LAN to pass through the firewall. INTIF=eth1 # network interface connected to your LAN INTNET=192.168.1.0 # network associated with your LAN /sbin/iptables -A INPUT -i $INTIF -s $INTNET -j ACCEPT /sbin/iptables -A INPUT -s $INTNET -j DROP # dump anything else claiming to be on LAN --Rob Mitchell, Edmund wrote: >Hello all > >I'm new to iptables, (and no hotshot with Linux, either), so I'm hoping >someone can point me in a good direction for some docs on iptables basics - >I just need to get it to accept tcp packets from port 6000, and I don't know >the necessary voodoo. > >Thanks > >Edmund > > >------------------------------------------------------------------------ > >Want to buy your Pack or Services from MandrakeSoft? >Go to http://www.mandrakestore.com >
