ok so this is wat i want
i got a 56k external modem
i hav configured it so that works now what i want to do is share my 56k modem so windows xp can use the internet thro my computer i hav them networked alright wen they both hav windows xp but i changed to linux redhat9.0 and i am a complete newbie i hav searched on how to do it and cant find anywhere that has a tutorial on it
so can someone tell me a step by step to be able to share my internet connection thanks
ohh yea and i can ping the windows xp machine from linux but i cant ping the linux machine from the xp machine it says destination not reachable
and my linux box ip is 192.168.0.1

I could tell you how to do it if the machine with the Internet connection was running XP, but I don't know how to get Red Hat to share the connection. Sorry

Not being able to ping the Linux machine from the XP machine sounds like a firewall problem as you can ping the other way without any problems. Try disabling iptables on the Linux machine while it's not connected to the Internet and you'll probably find you can ping it.

well thanks mate it was the firewall i turned it off and can ping perfect now but wat about gettin redhat 9.0 to share the internet

lol about 1month ago i wanted to no how to connect to the internet thro xp because my internal winmodem wasnt compatible
so i wanted to connect thro xp but now i hav a exxternal modem that works on rh9.0 so i want xp to connect thro RH9.0

I'm absolutely certain someone here will be able to tell you both how to share the Internet connection via RH and how to configure your firewall to allow all traffic from XP box.

what u need is to make a linux router...using the same "firewall" --iptables...

do a search for such and if anything i'll try to be of assistance...basically u want to accept all requests on the ethernet device and forward them to the ppp device...and allow the responses back through

the linux machine will be the gateway of the xp machine -- so as to allow all traffic to go through it.

let i know

If it helps any, there's a thread on here where someone has posted their IPtables setup: http://www.linuxquestions.org/questi...hreadid=107503

They're having problems with it DNS wise, but it may be worth using it and keeping an eye on that thread for someone posting a solution.

thanks DoubleOTeC could u tell me how to do it?
i allowed eth0 in the firewall settings and the rest of the firewall is off so now to make the gateway is all i need to do is put the gateway 192.168.0.3 on the RH9.0 machine then will xp be able to access the internet

com on does anyone know i need it

Sorry i haven't responded...i've been away from tech for a while....

You said that the firewall aspect is configured (the thread suggested above may have been helpful) therefore all u need to do is set the XP box's gateway to the IP address of the linux Box. If all requests go through to the eth0 on the linux box then they according to the firewall rules should be forwarded to the ppp device

let i know....( i hope i answered the right question )

nope i put it in the winxp machine and didnt work so maybe i havnt confirgured rh propely plz anyone else can help?

i will need help on that forwarding stuff that your talkin about remembers im a newbie so can u explain it step by step plz i need this

create a script with the following in it..

#!/bin/sh
IPTABLES=/sbin/iptables
echo "1" > /proc/sys/net/ipv4/ip_forward
$IPTABLES -P INPUT ACCEPT
$IPTABLES -F INPUT
$IPTABLES -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
$IPTABLES -A INPUT -m state --state NEW -i ! eth0 -j ACCEPT
$IPTABLES -A INPUT -j DROP
$IPTABLES -P OUTPUT ACCEPT
$IPTABLES -F OUTPUT
$IPTABLES -P FORWARD DROP
$IPTABLES -F FORWARD
$IPTABLES -t nat -F
$IPTABLES -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -ACCEPT
$IPTABLES -A FORWARD -i eth1 -o eth0 -j ACCEPT
$IPTABLES -A FORWARD -j LOG
$IPTABLES -t nat -A POSTROUTING -o eth0 -j MASQUERADE

i took this example from the the thread mentioned above....in your case i believe that the eth1 should be replaced with the name of your ppp device

execute the file and see if that works....

let i know
