Hi Cisco Community.
I have a site to site VPN set up using an ASA 5505 (remote) and a checkpoint firewall managed by a third party (head office). I cannot ping either the external interface or the internal interface of the remote firewall. From the remote location, I am able to ping and connect to devices located at head office. Unfortunately at this moment in time I only have the firewall at the remote site so I cannot try and ping anything else behind it.
I am concerned as we will be replicating data and syncing between the two so communication between the two locations needs to be bi-directional.
I think that I have configured ICMP to be allowed at the remote end, and the third party managing the head office firewall say they are allowing it through too. Interesting thing is that I can ping the router that the ASA at the DR site is connected to (it's route outside) and I am getting a response, so ICMP is indeed getting back through. I'm just wondering is there is anything I have overlooked on the configuration of the ASA?
Any help would be greatly appreciated. The running configuration is attached below. Thanks in advance to anyone who may be able to help.
