Did you enable ICMP inspection in your service policy rules under default inspection traffic?

Have you tried to ping hosts on the other side of the interface? And not the interface it's self?

Akshay,

Here is my icmp commands..

ciscoasa# show run icmp
icmp unreachable rate-limit 1 burst-size 1
icmp permit any AIXPrivate
icmp permit any ESXHosts
icmp permit 10.10.0.0 255.255.0.0 echo-reply Ranger

Andre..

Here is my inspect config

policy-map type inspect dns preset_dns_map
 parameters
  message-length maximum client auto
  message-length maximum 512
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
  inspect sqlnet
  inspect skinny 
  inspect sunrpc
  inspect xdmcp
  inspect sip 
  inspect netbios
  inspect tftp
  inspect ip-options
  inspect icmp

I am able to ping host on other network.. just not the gateway.. which is my ASA subinterfaces..

I don't think the asa will allow icmp to the interface. If you can ping the hosts, why would you want to ping the interface? You already have traffic successfully traversing the subinterfaces.

Hi,

As i had mentioned in my last comment, please add the below command. As you have already configured 'permit icmp' then you need to explicitly allow all the source ips from which you need to allo pings to your interface ip or rest of the ip for interface pings would be implicitely dropped. Therefore :

icmp permit <source-ip(from whrere you are pinging sub-interface)> 255.255.255.255 <sub-interface-name>

You have only configured :

cmp permit any AIXPrivate
icmp permit any ESXHosts
icmp permit 10.10.0.0 255.255.0.0 echo-reply Ranger

- any body is allowed to ping from AIXPrivate

- any body is allowed to ping from ESXHosts

- Only echo-reply is allowed when ping is initiated from ASA with Ranger as source interface.

Hi,

Could you please check  the output of 'show run icmp' from the ASA. Please provide the output here.

try adding 'icmp permit <source-ip> <255.255.255.255> <sub-interface-name>'

Please let me know if ping works after adding this.
