Hi Jay! Thanks to your help I am making progress on my networking problems. 1. Now I have internet connectivity by adding the GW to the eth0-DHCP configuration. 2. Now I also can bring up the LAN side on eth1 by removing the GW from the settings and using 192.168.0.1 ip address and 255.255.255.0 mask. 3. I have a Fedora PC connected to eth1 using a crossover cable. Before I had internet connectivity with the following settings on the client PC (adjusted for new network schema): IP: 192.168.0.50 Mask: 255.255.255.0 GW: 192.168.0.1 (= eth1 on PC connected to cable modem) DNS: same entries as on PC connected to cable modem. Then I adjust /proc/sys/net/ipv4/ip_forward and also modify /etc/sysctl.conf so that I do not have to echo to proc after each reboot. Then I type (as root) on the PC connected to the cable modem: iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE iptables --append FORWARD --in-interface eth1 -j ACCEPT So, when I still was at FC1 it worked like a charm. Now as FC3 the following happens at the client PC (192.168.0.50): 1. ping 192.168.0.1, OK works! 2. ping the IP number of either of the DNS servers, OK works! 3. ping the charter.net GW, OK works! 4. ping a non-IP, thus requiring DNS name resolution e.g. ping www.cnn.com, the I get: www.cnn.com unknown host. So for some reason I do not get DNS to resolve host names even though everything else now works. /etc/resolv.conf is the same now on 192.168.0.1 and 192.168.0.2 netstat -rn on 192.168.0.1: Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 68.187.12.0 0.0.0.0 255.255.252.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 68.187.12.1 0.0.0.0 UG 0 0 0 eth0 iptables -L -t nat Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- anywhere anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination Any suggestion? Thanks in advance.
