gateway newbie questions

[Marty Landman]

I've got an office network which is sharing the dial up connection on my 
RH9 box - gui installed - with the other computers. Occasionally one of my 
kids will do things that hog up bandwidth. The way I currently deal with it 
if she's not around is pull the cable out of the switch. :)

Was hoping that there would be an easier, software driven way.

Added this line to /etc/hosts.deny

ALL : squag

The file is empty otherwise as is the /etc/hosts.allow file. Squag is her 
computer's name in the /etc/hosts file. BTW host names are not case 
sensitive, are they? I don't have to reboot to have hosts.deny take effect, 
do I? Am just wanting to shut down internet connection sharing for that one 
computer; or is there a way to put a bandwidth quota on it?

....

Also, here is how I got the gateway working - from a yolinux article iirc:


/sbin/iptables --flush
/sbin/iptables --table nat --flush
/sbin/iptables --delete-chain
/sbin/iptables --table nat --delete-chain
/sbin/iptables --table nat --append POSTROUTING --out-interface ppp0 -j 
MASQUERADE
/sbin/iptables --append FORWARD --in-interface eth0 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward

Mind you I don't understand these commands really - all feedback most welcome.

Thanks in advance.

Marty
