Natting issue with new subnet.

L3 Networker

I am applying destination nat. Natting public ip(untrust zone) to internal ip(trust zone). Public ip subnet is /28.

When access public ip in the monitoring logs it shows me dst zone as Untrust whenit should show dst zone as Trust.

I have policy in place and natting but its not hitting any policy and goes to expicit deny.

Hi there,

 

Did you apply the appropriate security policies and NAT policies in place for destination NAT?

 

Generally there are 2 places to check in your configurations:

 

NAT Policy:

Destination zone : Pre-NAT IP

Destination address : Pre-NAT IP

Destination Translation : Post-NAT IP

 

Security Policy

Destination zone : Post-NAT

Destination address : Pre-NAT

Source zone : Pre-NAT

 

I attached an illustration of diagram below for your reference. Hope it clarifies your understanding of destination NAT
