- IPSec Traffic Through Cisco ASA: Understanding NAT and Inspection Scenarios
Conditions: ASA is doing NAT ASA is configured with inspect ipsec-pass-thru Required Configuration: Enable IPSec inspection on ASA Allow UDP 500 on outside interface (if R7 is initiator) What Happens: ASA inspects ISAKMP (UDP 500) negotiations ASA dynamically opens holes for ESP and or UDP 4500 based on negotiation Benefit:
