How to Change the SNAT and Health Check IP Addresses Used When Connecting to Servers?
About
What is SNAT?
SNAT (Source Network Address Translation) is a type of NAT (Network Address Translation) that changes the source IP addresses of network traffic. When traffic is routed to Backend Services, TR7 automatically performs NAT and forwards the traffic through an IP within its own network. These IPs can be changed at any time.
What is Health Check IP Adresses?
When performing health checks on Backend Services on TR7, it conducts the health check using an IP within its own network. Additionally, it is also possible to perform the health check for a Backend Service using a different IP and Port. These IPs can be changed at any time.

Changing SNAT and Health Check IP Adresses
Step > 1
Follow the steps "Traffic Manager > Backend Services" to open the edit form of the relevant Backend Service or to add a new Backend Service.
Step > 2
Activate the "Details" section.
Step > 2.1
For SNAT modification, "SNAT" is changed to "Use Device IP". From the row below, an IP address defined on TR7 can be selected. This allows the IP address used during the connection to the relevant Backend Service to be changed as needed.
Step > 2.2
For health check IP modification, "Health Check Source IP" is changed to "Device IP". From the row below, an IP address defined on TR7 can be selected. This allows the IP address used during the health check of the relevant Backend Service to be changed as needed.
Step > 2.3
To change the health check target address, "Use different IP for health check" is changed to "Different IP", and the IP:Port information for the health check is entered. By default, the health check is performed on the Backend Service's IP:Port. However, to consider the Backend Service as healthy, it might be necessary to check a different IP-:Port. In such cases, the health check target address information should be provided.
In this way, the interface and IP address used by TR7 for server connections can be easily managed via the web management interface.
