I,m running slack current with kernel 2.6.16.18 I,m connected to a cablemodem trought ethernet, I had 2 NIC in this box the one that is working with the cablemodem is configure as DHCP the other one, the one that supposed to give internet to the rest of my network is configure as static IP, this is my ifconfig -a

I already did some masquerade with iptables, and enable rc.ip_forward from /etc/rc.d and my network still can,t connect to internet. If I ping the address 192.168.0.1 it does respond at me, but still can,t connect any help?

Try generating a masquerading/nat firewall script that you install on your server. Try http://www.slackware.com/~alien/efg/ where I have Easy Firewall Generator installed. Go through the screens, fill out your configuration and save the generated script as and make it executable: .
If an executable file with that name exists, Slackware will automatically run it with the "start" parameter on boot. That should get your firewall going.

If you run a DHCP server on that server, your client computers don't need static IP's. The Slackware dnsmasq package offers a simple easy to setup DNS/DHCP server for small networks.

The problem is, if I delete all entry in rc.inet1.conf for eth1 (the second NIC) and supposed to put dhcp as "yes" when I reboot or reboot inet1 the second nic eth1 stay without IP, so where I supposed to ping? it should at least get a dinamic IP but it doesn,t. And If I put at static IP to eth1 the network still can,t connect to my box even if I put that IP as gateway.

Of course you have to give eth1 a static IP address. It is the IP address for your internal server and it could be running an internal DHCP service itself. So, your solution of giving it 192.168.0.1 is good.
Only the external (internet-facing) card gets it's IP address from the ISP's DHCP server.

Yes but still isn,t working, with either of the firewall I use from the site you gave me, I try to configure the rest of clients to use a static IP also and 192.168.0.1 as gateway, but still no luck....

I don,t know what,s happening.

Thanks my network is now working, I check out the post configuring slack as gateway and that helped a lot, a linux box still doesn,t connect but the rest of machines win xp connect well.

thanks...

Are you saying that your router can not connect to the internet but the computers behind it can connect to the internet though it? I think you might have done something strange in your iptables.

Please post the output of 'iptables -L'
