hi there, here's my problem: I have red hat 7.2 up and running. 2 NIC LAN card (eth1) : 192.168.0.1 CABLE MODEM nic (eth0): 217.70.66.140 (using dhcp from isp) I want to allow all computers from 192.168.0.* to access the internet. My iptables look like this: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination My route looks like this: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 217.70.66.0 * 255.255.255.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo default router-net-217- 0.0.0.0 UG 0 0 0 eth0 what must i change to put my box as a gateway ? thanks in advance

You probably already havedone this but I didn't see it any where above. Have you enabled routing? You can do it by editing the file: /etc/sysconfig/network including the line FORWARD_IPV4="yes" You can also set this up in linuxconf the same place you set up your default gateway. I hope this helps Paul

Just a word of caution, I found in my installation that after setting stuff in linuxconf, somehow it did not permanently register so I had to edit the files like /etc/sysconfig/network-scripts/ifconf-eth0 to ensure that the settings always started.
