- IP Inspects -- Why do we need them? - Cisco Learning Network
ip inspect name FWOUT udp ip inspect name FWOUT icmp ip inspect name FWOUT ftp This will tell our IOS firewall to properly inspect and handle ftp traffic In other words, this adds the some specific protocol intelligence that is required to handle ftp What about other protocols, like SMTP? Shouldn’t that work since there are no secondary
- Zone-Based Policy Firewalls 5 step process - Cisco Learning Network
My example PMAP action will be to inspect the class map Here you can also define the policy action to pass or drop traffic Step 5 you will create a service policy by naming it and identifying the flow in which traffic is going and identifying the zone membership (zone-membership) and use the names of the zones we created
- 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:

- Zone Based Firewall Part 1 - Cisco Learning Network
Inspect Allows for stateful inspection of traffic flowing from source to destination zone, and automatically permits returning traffic flows even for complex protocols, such as H 323
- Class Map [match default-inspection-traffic]
Hi Atul, Sure you can do that By default, class-map inspection_default is assigned to global_policy policy-map and to view the protocols inspected by default on ASA use following command ASA1# sh run policy-map global_policy ! policy-map global_policy class inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect rsh inspect rtsp inspect esmtp

Configure ASDM to show the commands that are going to be applied to the device, then configure ICMP inspect using ASDM so you can see the command that is being used
- Question about debugging or logging of inspection
Outside of using packet tracer to test if a packet is being will be dropped or not, is there a way to debug or see logging messages when a packet is dropped due to an inspection policy?
