Greetings O_O
I have a home server ( red hat 9 - 192.168.20.3 ) and a PC ( WinXP and slack 9.1 - 192.168.20.1 ). The server has internet - 512k LAN - and shares the net to my PC with this line in /etc/rc.d/rc.local
iptables -t nat -A POSTROUTING -s 192.168.20.1 -j MASQUERADE
In the WinXP options, I only type my IP, Netmask, Gateway(192.168.20.3) and DNS servers from my ISP and I have net. With slack, I can ping the server, and I see that in ifconfig they are connected, but I dont have internet.
Thats it, peace
