Hi, Tell me if I understand this right. For a packet that is not for local host, but comes in on one interface and goes out on another; Will that packet traverse PREROTING, FORWARD and POSTROUTING on _both_ underface, or will that packet traverse PREROTING, FORWARD and POSTROUTING only once, where PREROTING is when a packet "is in" the incoming physical interface, and is in FORWARD and POSTROUTING when the packet "is in" the outgoing interfave? regards, Kjell
