Hello List, This is my first mail to the Netfilter List. I am a newbie to IPTables, so please be gentle :-) I have a Red Hat Linux 7.3 box running iptables-1.2.5-3. I am using iptables primarily for Source NAT. The machine has two IP Addresses eth0 : 172.25.8.130 eth0:0 : 172.25.8.125 I am terribly confused with the OUTPUT chain. I have read from the documentation that the OUTPUT chain is used for locally generated packets. The machine always uses the IP Add of eth0 for any locally generated packets. How do I configure the OUTPUT chain such that the machine uses the IP Add 172.25.8.125 when it requests for specific ports or protocols. For eg, I want the machine to use the Source IP as 172.25.8.125 whenever it runs a DNS query. How do I go about this?
