Hi guys,

the problem:

Ive got a network with several windows comps and 1 linux server
they are all connected to my switch
the linux server -> eth1 = adsl modem connection (ppp0)
eth0 = connection to switch (lokal network)

to share my internet i did:

I used this file for iptables
w w w.ecst.csuchico.edu/~dranch/LINUX/ipmasq/examples/rc.firewall-2.4

EXTIF="ppp0"
INTIF="eth0"

(then run it -> sh rc.firewall-2.4 ) looks all ok!

I also:

changed the parameter of ip_foward to 1 in /etc/sysctl.conf
then
echo "1" > /proc/sys/net/ipv4/ip_forward


and

i tried to turn off the firewall in the setup menu (lokkit)
but everytime I change it to off and look at it again -> its high again... (wtf?)

I can ping from windows to linux and linux to windows

I can ping the ip of my adsl connection from my windows comps.

but I can't get on the internet with windows.

windows settings :192.168.0.x - 255.255.255.0 gateway=192.168.0.1
linux: 192.168.0.1 (eth1)

please help!! what did I do wrong or forgot?
thx

You may have fogotting to setup Masquerading.

Also, for RedHat, you do not need to use the rc.firewall-2.4 script.

To setup IP Forwarding and Masquerading (Internet Connection Sharing) in RedHat, take a look at these threads.

To debug your network, use the following commands.

To display network device information
To display the iptables rules.
To display your routing table.

thx!
Its working now :-)
