SNAT=None client source IP is self IP

Where do you see a self ip as a source? If SNAT is not set the only traffic sourcing from self ip should be monitors testing availability of the nodes (backend servers).

This was my vserver config ( created http vserver to test) - (Active)(tmos) list ltm virtual mo_test_80-vs ltm virtual mo_test_80-vs { destination 10.4x.x.2:http ip-protocol tcp mask 255.255.255.255 persist { motTest { default yes } } pool mo_test-80 profiles { fasthttp { } } snatpool Default-SNAT }

 

Changed to ltm virtual mo_test_80-vs { destination 10.x.x2:http ip-protocol tcp mask 255.255.255.255 persist { motTest { default yes } } pool mo_test-80 profiles { fasthttp { } } }

 

I am getting source IP as per default-SNAT. I have changed monitor interval to 1000 second so it is not monitor traffic.
