How can i do to share a dialup internet connection between linux and windows??
I use linux for connecting.
I have another PC with windows, connected with the linux machine (LAN).

Is possible to surf with the windows machine when ia am connected in linux??

Same problem here, i enabled ip_forward en my kernel (2.6.5), installed routed and set up iptables, but still nothing and i did it the same way with Slackware some time ago and it worked, What else do i need to do it with Gentoo?

manucorrales,

If you have a single public IP address, the linux box will need to provide network address translation so that packets from all the PCs you have appear to come from the public IP.

You need iptables and a setup script.

If you have at least two spare public IPs, you only need forwarding and PPP.

Try using shorewall. It's a good front-end for the iptables commands. You can configure it to do NAT for any computer using it as the gateway. This way, you only need one public IP. Read through the man pages for shorewall, or go to http://www.shorewall.net/1.4/two-interface.htm and follow the directions there.
