If someone is so nice to leed me step by step i would be greatful. Thanx in advance !

 

Okay this is a quick and dirty guide, am sure there are more comprehensive ones you can get on the net

Enable forwarding edit /etc/sysctl.conf and make this change

Code:

net.ipv4.ip_forward = 1

Create a quick firewall to block internet users from getting to you and to NAT you lan connections out, edit /etc/sysconfig/iptables

Code:

*raw
:PREROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT

*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A POSTROUTING -o ppp+ -J MASQUERADE
COMMIT

*mangle
:PREROUTING ACCEPT [0:0]
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
COMMIT

*filter
:FORWARD DROP [0:0]
:INPUT DROP [0:0]
:OUTPUT DROP [0:0]
-A INPUT -i lo -j ACCEPT
-A INPUT -i eth1 -j ACCEPT
-A INPUT -i ppp+ -m state --state ESTABLISHED,RELATED -J ACCEPT
-A FORWARD -i eth1 -o ppp+ -j ACCEPT
-A FORWARD -i ppp+ -o eth1 -m state --state ESTABLISHED,RELATED -J ACCEPT
-A OUTPUT -J ACCEPT
COMMIT

 

thanx for guide i will try and see is it working

 

i make it exactly as you discrybe but nothing works

 

Did you reboot ?
What does this show

Code:

cat /proc/sys/net/ipv4/ip_forward
