difference between NAT Pre Rules and Post Rules

L1 Bithead

Please can someone explain when to use Device Groups - Policies - NAT - Pre Rules vs Post Rules.  I cant seem to find any documentation on this.  

 

Thanks

Hi @ismailsh ,

 

Pre-rules are ordered on the NGFW before local rules, and post-rules are ordered after local rules.  Although this doc references the security policy, Panorama pre- and post-rules function the same for all policies.  Check out the pic in the doc below:

Beacon has free training, Managing Firewalls at Scale, that is an excellent online tutorial for Panorama.  It covers this and many other topics.

 

Thanks,

 

Tom
