SNAT Status
screen displays the ZyWALL’s current
source NAT (SNAT) flow. Click a function box to see the corresponding active SNAT rules. The
ZyWALL checks if a packet matches an SNAT rule’s criteria by following the order of the flow as
shown from left to right. Once a packet matches the criteria of an SNAT rule, the ZyWALL takes the
corresponding action on the packet and does not perform any further SNAT flow checking.
