Hi I have a dial up connection and want to use linux to connect to the net, then have windows boxs hanging off it. I just looked at the "Masquerading Made Simple HOWTO"
and it says to do the following modprobe ipt_MASQUERADE # If this fails, try continuing anyway iptables -F; iptables -t nat -F; iptables -t mangle -F iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -m state --state NEW -i ! ppp0 -j ACCEPT iptables -P INPUT DROP #only if the first two are succesful iptables -A FORWARD -i ppp0 -o ppp0 -j REJECT Before I do it, do you think it is very secure? All I want to be able to do through the linux box from the windows machines at the moment is to surf the net, collect/send mail and ssh out(I dont want to be able to ssh to this box from the net). What do I need to add to allow only the services to/from the net.
