Symptoms

Deterministic NAT state information incomplete for HSL log format, could possibly result in incorrect reverse and forward map for dnatutil when using with HSL logged state information.

Impact

Reverse and forward map could be incorrect when use with HSL logged deterministic NAT state information.

Conditions

Found to affect VIPRION B2250 blades with HTSPLIT enabled, when using dnatutil with HSL logged deterministic NAT state for reverse map.

Workaround

Use LTM logged deterministic NAT state information for reverse or forward map.

Fix Information

HSL logged deterministic NAT state information can be use to correctly forward and reverse map.
