Hello, I am a fairly new person in Linux networking. The issue I got some responses was as follows: ------------------------------------------------------- I have had some good help to enable IP forwarding on my Redhat 9 gateway with the rule: [CODE]iptables -t nat -A POSTROUTING -o eth1 -j SNAT --to-source 172.16.3.10[/CODE] This rule forwards the traffic from the internal network (172.16.4.0/24) to the outside trhough the NIC with IP address 172.16.3.10. Problem: But I feel that the internal IPs are being forwarded with the IP address of the external NIC of the gateway. It would be helpful if I could have a way to keep the internal IP address (172.16.4.0)as it is without being substituted with the gateways IP address(172.16.3.10). This is because I want the external users to see the internal machines(172.16.4.0 network) as it is. Please advise. ---------------------------------------------------------- Adding to my question above:- The redhat 9 gateway forwards traffic between two private networks. The network topology goes like this: 172.16.8.0/24 ------------ router ----------- 172.16.3.0/24 ------- Redaht 9 ------- 172.16.4.0/24 Is there a way that folks from the 172.16.8 network see the 172.16.4 network machines as they are, without being substituted with the redhat 9 gateway IP of 172.16.3.10 ? This is a strictly private network setup for doing some tests. Thank You. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
