LABEL DESCRIPTION
SNAT Flow This section shows you the flow of how the UAG changes the source IP address for a packet
according to the rules you have configured in the UAG. Click a function box to display the
related settings in the
SNAT Table section.
SNAT Table The table fields in this section vary depending on the function box you select in the SNAT
Flow section.
The following fields are available if you click Policy Route SNAT in the SNAT Flow section.
# This field is a sequential value, and it is not associated with any entry.
PR # This is the number of an activated policy route which uses SNAT.
Outgoing This is the outgoing interface that the route uses to transmit packets.
SNAT This is the source IP address(es) that the SNAT rule uses finally.
The following fields are available if you click VPN 1-1 Mapping SNAT in the SNAT Flow section.
# This field is a sequential value, and it is not associated with any entry.
Source This is the original source IP address(es).
Destination This is the original destination IP address(es).
Outgoing This is the outgoing interface that the SNAT rule uses to transmit packets.
SNAT This is the source IP address(es) that the SNAT rule uses finally.
The following fields are available if you click 1-1 SNAT in the SNAT Flow section.
# This field is a sequential value, and it is not associated with any entry.
NAT Rule This is the name of an activated NAT rule which uses SNAT.
Source This is the original source IP address(es).
Destination This is the original destination IP address(es).
Outgoing This is the outgoing interface that the SNAT rule uses to transmit packets.
SNAT This is the source IP address(es) that the SNAT rule uses finally.
The following fields are available if you click Loopback SNAT in the SNAT Flow section.
# This field is a sequential value, and it is not associated with any entry.
NAT Rule This is the name of an activated NAT rule which uses SNAT and enables NAT loopback.
Source This is the original source IP address(es). any means any IP address.
Destination This is the original destination IP address(es). any means any IP address.
SNAT This indicates which source IP address the SNAT rule uses finally. For example, Outgoing
Interface IP means that the UAG uses the IP address of the outgoing interface as the
source IP address for the matched packets it sends out through this rule.
The following fields are available if you click Default SNAT in the SNAT Flow section.
# This field is a sequential value, and it is not associated with any entry.
Incoming This indicates internal interface(s) on which the packets are received.
Outgoing This indicates external interface(s) from which the packets are transmitted.
SNAT This indicates which source IP address the SNAT rule uses finally. For example, Outgoing
Interface IP means that the UAG uses the IP address of the outgoing interface as the
source IP address for the matched packets it sends out through this rule.
