Dear Users, please help me to understand the processing of packages when a DNAT-rule is setup. With DNAT on a Router the destination address is changed so a package with SRC: 1.2.3 and DST 4.5.6 will become SRC: 1.2.3 and DST 7.8.9 If the receiver answers it is SRC: 7.8.9 and DST 1.2.3 so if this packages is arriving on 1.2.3 it will get dropped as the sender was talking to 4.5.6 and not 7.8.9. Now to my question - is a SNAT-rule mandatory on the Router or is there some other process of "reverse-NAT" the answer packages to the initial sender? I want to understand what is happening with the packages and answer-packages in detail. thank you in advance Stefan -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
