The packet tracer command was introduced in 7.2(1).
You could upgrade the ASA to 7.2(4) and its a stable version in the 7.2 trail.
Here's more information on the command:
http://www.cisco.com/en/US/docs/security/asa/asa72/command/reference/p_72.html#wp1724426
Please collect the bidirectional captures as this gives us exact details on whats dropping the packets.
Another suggestion here:
You could also collect some syslgs on the pix in debugging level. Reproduce the issue. Then check the logs to see if you find something there.

Hi,
To start with, please try the following:
1. Ping 192.168.2.5 from the firewall annd make sure its successful.
2. Try a packet tracer and check if its successful
packet-tracer input outside tcp
3. apply captures on the inside and the outside interface and check to see if packets are going through the firewall in both directions.Please paste the output of the capture here. Please refer to the link below for info on how to apply captures on PIX

My Asa version 7 and ASDM software does not support packet tracer.
If you can provide me a useful link to upgrade to versions supporting packet tracer, that would be good.
I have tried version 5.2 for ASDM on a spare ASA with similar version but could not get packet tracer loading...
I'll try googling and would appreciate your help
thanks
