VPN CLIENT PROBLEM

Question

Hi
I have a problem with ping in VPN Client,
In this senario, the VPN client should be able to ping PC-4 through ASA-1 (Site-A)but it could not.
The router is able to ping Z.Z.Z.0/24.
The Tunnel and VPN client are working.
1. PC-1 can connect to ASA-1 and ping Network 20.20.0.0/16 and 10.10.10.0/24 but cannot ping PC-4.
2. PC-2 can ping PC-1 and PC-3 but cannot ping PC-4.
3. If PC-3 gateway be 10.10.10.1 , It can ping Z.Z.Z.2.
4. If PC-3 gateway be 10.10.10.20 , It cannot ping Z.Z.Z.2.
5. ASA-1 can ping ASA-2 and 10.10.10.1/24 but cannot ping Z.Z.Z.2.
6. ASA-2 can ping ASA-1 and Z.Z.Z.2.
This is my config on ASA-1 and ASA-2:

Answer 1

Hi,
My suggestion to your puzzle  is to  either load your ASDM real time log and observe the logs while one host tries to ping each other and take notes on the log , this should provide you with  information  and some clues on what the issue could be.  You may also try  to packet capture in ASA-2  , either way,  I would start with easiest one which is  realtime log on ASDM.
Could you provide the folloing:
1 - Post output of    c:\ipconfig /all    from PC-4  z.z.z.2/24
2 - Post output of     show ip route     from Router   where PC-4 subnet is routed from
Regards
