Hello friends: We are using iptables under Linux kernerl 2.6.14. We need to do this: Our server has 2 ip's. One is used only for SMTP outgoing and the other for all the rest. All is running fine except that our smtp outgoing IP has problems conecting ONLY to one smtp server. What we want to do is: all from our server to that smtp server change the source IP and use the other one that we have in our server. Do i explain ok? My english is not very good :( We are trying this with this: iptables -t nat -A OUTPUT -p tcp -j SNAT -d ip_wanadoo --to nuestra_otra_ip But: iptables: Invalid argument We are using OUTPUT becouse we think that it is the correct. Can this be done? What are we doing badly? A lot of thank's -- Rubén Navarro Huedo http://www.palotes.com http://www.cabodesantapola.org
