A BIG-IP has a virtual server at 150.150.10.10:80 with SNAT automap configured. This BIG-IP also has a SNAT at 150.150.10.11 set for a source address range of 200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to the virtual server, what is the source IP address when the associated packet is sent to the pool member?
When a virtual server is configured with SNAT automap, it automatically translates the source IP address of the client to one of the self IP addresses of the BIG-IP system that is in the same VLAN as the pool member. This ensures that the return traffic is properly routed back through the BIG-IP system. Therefore, the source IP address when the packet is sent to the pool member will be the floating self IP address on the VLAN where the packet leaves the system.
Answer is B
why answer is C?, I think should be B. 150.150.10.11
C : SNAT within a VS takes precedence on a seperate SNAT listenner. So automap is applied
A virtual server with SNAT Automap takes precedence over matching the NAT https://my.f5.com/manage/s/article/K62579650
