this is a udp datagram which originate from one of the computers in my local lan, not the firewall however, the SNAT is on the POSTROUTING table which means (as far as i know) that it is also applied to packets originating from the firewall ( i.e. the packets from the OUTPUT chain travel to the POSTROUTNING chain) pls. correct me if i'm wrong. thanks, erez.
