The client is using CheckPoint R75.x and we have established a site-to-site VPN Connection. The VPN on our end was setup using AWS.
Were are able to ping from AWS to Checkpoint and receive a response, however, when the client pings from CheckPoint, the packets pass their firewall and into the tunnel but there is no response from AWS side.
The routing and rules are all setup correctly.
We are using 1 tunnel and AWS provides an outside and inside IPv4 cidr for the tunnel. The client used the outside cidr but wasn't sure what to do with the inside cidr. Does the inside cidr need to be added somewhere in CheckPoint?
Is there another step or solution we can take to address the above issue in terms of no receiving a response back?
