Hi Atul, No - inspection and state tables are actually two different things in the ASA. As mentioned, inspection refers to protocol/payload analysis of the supported protocols (if enabled of course), which dynamically can punch the necessary firewall openings and/or perform validation of the traffic, whereas the state table is populated based on the configured access-lists, or in …

I am trying to configure new cisco router c1111-8p. Found I do not have option to configure ip inspect & zbfw. Below is the router detials. Is there any other option to configure inspection? System image file is "bootflash:c1100-universalk9_ias.16.08.01.SPA.bin"! Suite License Information for Module:'esg'

The factory default configuration of an ASA already contains that for some protocols. On IOS routers, you may configure with "ip inspect" or "ipv6 inspect" commands. Here is a small (maybe not very useful) example: ip inspect name sillytest ssh. ip inspect name sillytest dns. ip inspect name sillytest ftp! ip access-list extended blockall. 10 ...

Router(config-pmap)# class type inspect CLASS-MAP . 4c) Specfiy action of inspect for policy map. This is where we decide if traffic from our CLASS-MAP if will be inspected, passed or dropped. This action will be applied to our internal traffic or the ACL we created. The CLI should look like this. Router(config-pmap-c)# The action I will use is ...

ip inspect name FWOUT tcp. 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?

ip inspect name FWRULE icmp. ip inspect name FWRULE tcp. ip inspect name FWRULE udp. ip inspect name FWRULE http. ip inspect name FWRULE https. ip inspect name FWRULE ssh. ip inspect name FWRULE pptp. ip inspect name FWRULE ftp . But i can not enter it on ISR4431/K9 . So i think the new router ISR4431/K9 doesn't have ip inspect function, isn't it?

This relates to the policy map, all those inspect statements are the action take on the traffic identified/Matched by the class map. I'm concerned about the traffic which will be identified/Matched by the class map: Class-map inspection_default. match default-inspection-traffic . So what traffic is identified/Matched in the above class map ...

class type inspect OUT-SELF-CM. pass. class class-default. drop log. policy-map type inspect SELF-OUT-PM. class type inspect SELF-OUT-CM. pass. class class-default. drop log! zone security INSIDE. zone security OUTSIDE. zone security DMZ. zone-pair security OUT-SELF-ZP source OUTSIDE destination self. service-policy type inspect OUT-SELF-PM

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. (Works exactly like CBAC.)
