Dear All,

if A Host is in Corporate Zone and the Interface is in NAT mode what will be the source IP address of the packet received at another host that is in Internet Zone. (kindly Specify the rule of thumb for this)

Interface NAT, which basically is your interface NAT mode configuration, only works when you use the predefined trust and untrust zones. When you create custom zones, then you must use policy NAT. Refer to the following KB article.

For information related to policy NAT, refer to this KB article.

I hope this helps
