- 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
- Zone Based Firewall Part 1 - Cisco Learning Network
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
- 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:
- Intelligent Proxy in Cisco Umbrella how it works
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
- DNS Inspection problem - Cisco Learning Network
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? Here is the packet trace: ASA# packet-tracer input INT-WIRELESS-GUEST udp 192 168 254 172 65535 4 2 2 2 53 Phase: 1 Type: FLOW-LOOKUP Subtype: Result: ALLOW Config: Additional Information: Found no matching flow, creating a new flow Phase: 2 Type
- 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
- ASA5505: Host connected to inside interface cannot ping to outside . . .
As the first documentation has instructed there were two ways to permit icmp for version 7 2 and above, i chose the inspect icmp which is more flexible, which is shown above Also same-security-traffic permit intra-interface, for traffic to be allowed to be able to exit and return on the same interface with the same security level
- decrement-ttl - Cisco Learning Network
ASA doesnt decrement-ttl and we have to do it manually to see the interfaces of ASA when doing traceroutes I did put the "set connection decrement-ttl" command under the "class class-default" which is in the global policy-map and is applied globally using service policy Still when i m doing traceroute from the DMZ , I am not able to see ASA interfaces instead it jumps to R2 and then internet
