Why cant i ping any host/servers behing my Firewall Cisco 5505

Can anyone please help me to figure out what in my configuration of the Cisco asa 5505 is wrong or missing. I have multiple host behind my firewall these hosts run different websites on port 80. I am able to ping the server from one to another but I am not able to ping the servers from the internet. I am using static NAT. Is there a translation issue going on here. Please help me!

IP and ICMP are different protocols and the ACLs only allow the IP protocol or a subset.    So ICMP will hit the implicit "deny any any" at the end of the ALC and is dropped.  Try adding

access-list OutsideToInside extended permit icmp any host 10.0.2.104 eq echo

access-list OutsideToInside extended permit icmp any host 10.0.2.104 eq echo-reply

access-list inside_access_in extended permit icmp any any eq echo

access-list inside_access_in extended permit icmp any any echo-reply

Thanks for your response but when I try to add this to may config I get an error

"access-list OutsideToInside extended permit icmp any host 10.0.2.104 eq echo"

It is not allowing the "eq".  error "invalid input detected at marker"

Sorry the "eq" isn't needed.  should be able to enter the line as "access-list OutsideToInside extended permit icmp any host 10.0.2.104 echo"

Hi Ron,

I have found the solution!

Indeed I had to extend my access-list on my outside interface!!!

I have succeeded using ASDM.

First I created a NEW network object for each of my servers. When you create a new object you will be asked for the internal IP address and "this is where the magic happens" you have to set the NAT IP address (the external address) !!!

Secondly I extended my access-list on my outside interface by defining every server and the required service (echo, echo-reply) in the "Public server list". When I performed these 2 steps I was able to ping the server from the internet.

My access-list looks the following now:

access-list OutsideToInside extended permit icmp any4 object SERVER2003 object-group DM_INLINE_ICMP_2
access-list OutsideToInside extended permit icmp any4 object SERVER2002 object-group DM_INLINE_ICMP_1
access-list OutsideToInside extended permit icmp any4 object SERVER2004 object-group DM_INLINE_ICMP_0

 

object network SERVER2004
 nat (inside,outside) static 82.94.xxx.xxx
object network SERVER2002
 nat (inside,outside) static 82.94.xxx.xxx
object network SERVER2003
 nat (inside,outside) static 82.94.xxx.xxx

If you want to ping the servers from the internet then you need to allow ping in your outside acl.
