DESCRIPTION
This section shows you the flow of how the ZyWALL changes the source IP
address for a packet according to the rules you have configured in the
ZyWALL. Click a function box to display the related settings in the SNAT
Table section.
The table fields in this section vary depending on the function box you select
in the SNAT Flow section.
This field is a sequential value, and it is not associated with any entry.
This is the number of an activated policy route which uses SNAT.
This is the outgoing interface that the route uses to transmit packets.
This is the source IP address(es) that the SNAT rule uses finally.
This field is a sequential value, and it is not associated with any entry.
This is the name of an activated NAT rule which uses SNAT.
This is the original source IP address(es).
This is the original destination IP address(es).
This is the outgoing interface that the SNAT rule uses to transmit packets.
This is the source IP address(es) that the SNAT rule uses finally.
This field is a sequential value, and it is not associated with any entry.
This is the name of an activated NAT rule which uses SNAT and enables NAT
loopback.
This is the original source IP address(es). any means any IP address.
This is the original destination IP address(es). any means any IP address.
This indicates which source IP address the SNAT rule uses finally. For
example, Outgoing Interface IP means that the ZyWALL uses the IP
address of the outgoing interface as the source IP address for the matched
packets it sends out through this rule.
This field is a sequential value, and it is not associated with any entry.
This indicates internal interface(s) on which the packets are received.
This indicates external interface(s) from which the packets are transmitted.
This indicates which source IP address the SNAT rule uses finally. For
example, Outgoing Interface IP means that the ZyWALL uses the IP
address of the outgoing interface as the source IP address for the matched
packets it sends out through this rule.
