ASA 5520 blocked IPS

Hi Guys,

I need to know if there is a way to checl the IPs which are blocked to pass through the ASA 5520 firewall.

this firewall is doing the NAT for 3 IPs for me

  1. 192.168.20.21 -----NAT---->10.10.20.21
  2. 192.168.20.22 -----NAT---->10.10.20.22
  3. 192.168.20.23 -----NAT---->10.10.20.23

the number 2 & 3 are passing through but the first one cannot.

the ping is comming to the ASA and is stopped there

notice:

  • it has been working for 3 years
  • the initial config is done by some unproffesional guys and there is no rule on the firewall (permit any_any ) on all interfaces
  • ASDM is not configured to be used

I wonder to know if it is the firewall that is blocking the coming IP to the 10.10.20.21 IP ?

thanks

Gabriel;

The packets are being blocked incoming or outgoing direction? Have u checked the logs on the firewall? It could be very possible that this is being blocked before it gets to the firewall.
