Re: Destination NAT translation shows 0.0.0.0 on CSS 11503

Inayathulla,

I think the dst nat 0.0.0.0 packets are actually health-check packets for querying the servers state of healthyness, intiated by the CSS.

Usually there would be an Inport entry but nothing on the Outport, just a blank.

Happy if someone can give their input as well on this issue.

thanks
