Central NAT - DNAT

Hello,

I found out informatin thet if firewall works with Central NAT (DNAT) I can't select VIP as a destination address. It is true in profile-based mode when I manualy enable central NAT. But if firewall works in policy-based mode I cna choose VIP as the destination address.

Can you explain to me why it works differently in different NGFW mode?

Regards
