The deterministic NAT (DNAT) utility (dnatutil) might report incorrect reverse mappings for platforms with Intel Hyper-Threading Technology (HT) Technology split plane (htsplit) CPUs, which includes VIPRION and BIG-IP series 4000, 7000, 8000, and 10000 platforms.
Reverse mapping does not occur.
Using LSN pool with DNAT mode, and using dnatutil for reverse mapping.
Use the --flags attribute to manually provide the daglib flag attribute.
The deterministic NAT (DNAT) utility (dnatutil) now reports correct reverse mappings for platforms with Intel Hyper-Threading Technology (HT) Technology split plane (htsplit) CPUs, which includes VIPRION and BIG-IP series 4000, 7000, 8000, and 10000 platforms.
