Hi
My setup is like this:
ASA-5505-SITE-A (1.1.1.1)
ASA-5510-SITE-B (1.1.2.1)
On this side the ASA inside interface gooing into a router as WAN.
My LAN outside my routeur is 192.168.1.x
There is a VPN UP between SITE-A and SITE-B
From SITE-B I can ping everything to SITE-A
From SITE-A to SITE-B, nothing works.
Please help me.

Hi,
I am not sure I understand the setup from the above.
If you could share the configurations of the ASA firewalls (without public IP addresses etc.) then could look through the configurations.

On SITE-A my PC's IP adress come directly from the ASA 1.1.1.x
On SITE-B we use a router behind the firewall so my PC's adress are : 192.168.1.x
I can ping from SITE-B to SITE-A without any problem.
I cannot ping from SITE-A to SITE-B.
There is my 2 firewalls config.
Thanks

Hi,
Some observations,
So I am beginning to think that the router behind the Site B ASA is doing Dynamic PAT for the network 192.168.1.0/24 behind it. This would mean that all traffic from the 192.168.1.0/24 would be PATed to some IP address from network 1.1.2.0/24. This again would enable traffic to flow from Site B to Site A normally. Considering the Dynamic PAT done by the Site B LAN router would mean though that no connection initiation would work from Site A to Site B since you cant form connections through Dynamic PAT from the external side.
So my guess would be that you would have to
The above would most likely affect your Site B Static NAT configuration you did just in the other discussion here on the forums.
One other alternative is that you configure Static NAT for the hosts you need on the Site B router from 192.168.0.x to 1.1.2.x so they can be connected from Site A
Hope I made sense
