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.
Zone-Based Policy Firewall (ZBPF) (Zone Based Firewall) is the successor of Cisco IOS Legacy Firewall called (CBAC) Context-Based Access Control. Concept of ZBPF is zone, which groups different interfaces sharing the same security attributes or the same level of trust. Permissions for traffic forwarding is made between the zones or within a zone, not between physical interfaces.
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:
Hi Team, I have been having problems with DNS inspection and I can't seem to make it work. DNS resolutions to public DNS doesnt work. Any thoughts?

The solution is the "Intelligent Proxy" with "SSL Decryption" features. The intelligent proxy is the ability for Cisco Umbrella to intercept and proxy web requests to inspect the content of the web traffic. We can classify by categories which type of web traffic we want to proxy and apply SSL decryption.
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 ...
Hello, I have setup an IPsec vpn tunnel. All clients can ping to each other except from ASA itself. Is there a command to permit icmp traffic from ASA itself to vpn clients? ACLs? Thanks, Christian
So i think the new router ISR4431/K9 doesn't have ip inspect function, isn't it? Below is the show version on the new router: bb_router#show version Cisco IOS XE Software, Version 03.16.04b.S - Extended Support Release Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.5 (3)S4b, RELEASE SOFTWARE (fc1)
Techinically, a default class-map type does not exist. The only way that you can even begin to create a class-map type is by using the 'type' keyword (which is not a default in itself). Then, if you go that far with your command, you can't complete it without manually defining a class map, thus no default. If you just wanted to create a class map of a default type, match-all is the only answer ...
