Routing and everything is fine ..however if i try to ping the outside interface of the GW i am to reach it ..however if i try to reach the inside interface of the GW ..i am getting address spoof messages in logs and the traffic is getting blocked.. Is this by design that inside interface cannot be reached from any outside IP ?&nbsp; but it can reach any ip below that interface</P> Thu, 16 Apr 2020 12:52:25 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Inside-Interface-reachability-in-Checkpoint-Gateway/m-p/82116#M11378 LostBoY 2020-04-16T12:52:25Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Inside-Interface-reachability-in-Checkpoint-Gateway/m-p/82338#M11379 What's the precise topology?<BR />Can you provide screenshots of the topology configuration?<BR />Can you provide a screenshot of the error?
