Intervlan Routing is not working on Mgmt Interface for CheckPoint

Intervlan Routing is not working on Mgmt Interface for CheckPoint.

I have a New CheckPoint Firewall. On Mgmt Interface I configured L3 Sub Interfaces. In CheckPoint Mgmt Interface , need to have IP assigned , since I assigned One L3 Subnet on Mgmt Interface and created more Sub interface.

However I am not able to Ping any IP of that Subnet ( Mgmt Interface ) , from IT Network , but can Ping the Gateway from IT Network.

Also , Considering Mgmt Interface IP is 10.7.251.49 and a Server IP is 10.7.251.55 , they can Ping each other but not from IT Network. There is a OPSF between IT ( Cisco ) with CP firewall , I am redistributing the Mgmt Interface over OSPF.  

CP Firewall has the route to network from where I am trying to Ping to Server IP is 10.7.251.55.

Check routing first, and then policy on your Security GW.

Anti-spoofing / asymmetric routing would be topics to start investigating here.

Did not install the Smart Dashboard yet. Security GW is running on no policy using ( fw unloadlocal ) while I was preparing with single mgmt interface and install smart dashboard on that mgmt subnet.

[Chris_Atkinson]

Sounds like routing or possibly incorrect netmask setting perhaps?

[subrun_jamil]

From GAIA Portal is there any Anti-Spoofing Option ? I do not see any unless I missed.

[Chris_Atkinson]

It's defined based on the interface topology of the Gateway object in SmartConsole.

Smart Console is not setup yet just configured one  LAN Interface ( mgmt ) and OSPF for WAN.
