Hello, I have a problem. I have a linux box with two network cards configured with "real" ip numbers instead of private numbers. One is connected to the internet side and the other network card is connected to the fake side. I can ping both network cards from outside the internet but I cannot ping my interfaces from inside the lan. Ip forwarding is enabled. I am wondering if anyone knows how to fix this problem. All I really want to do is have a linux box in front of a hub which has a bunch of other machines behind it with real ip #s so that I can use ipchains to control incoming and outgoing traffics to those machines that are connected behind my firewall.

Do you have your networks specified in the /etc/networks file? This was the probelm that I had when I was trying to get my internal network to talk with the internet. Christopher Reimer On Thu, 2 Mar 2000, Paul Zimdars wrote:

No.. Its a Redhat 6.0 system with kernel 2.2.14 Let me add some more info..if I use private addresses 192.168.2.* whatever on the machines behind the lan side and the second nic card on the firewall they can ping each other and the machines inside the lan can ping the first and second interface on the firewall but not to any other place outside of the internet..from the firewall I can ping any place outside of the firewall.

Are you setting the default gateway for the other machines to point to the gateway. It sounds like a routing problem. SuSE's yast interface can handle adding these, and activating them. Doing a netstat -r should produce something like this: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default your.gateway 0.0.0.0 UG 0 0 0 eth0 Christopher D.
