Can't ping real IP in LAN w/ CheckPoint

By wai_pui_law ·
Dear all,

I have set up CheckPoint 4.1 on NT platform with the LAN and DMZ segments. All the servers in the LAN zone and the DMZ zones have been assigned real IP addresses.

The problem is that the users in the LAN cannot ping the real IP of "some" servers in the LAN zone, but they can ping the real IP of "all" servers in the DMZ zone. What is the cause for that only "some" real IP of servers in the LAN can be ping?

I want the users in the LAN can ping "all" servers' real IP addresses, is there any solution for that?

Best Regards,

WP

Can't ping real IP in LAN w/ CheckPoint

Hi there.

Sounds like a routing issue.

What is the IP address range and subnet masks you are using in both the LAN and the DMZ?

If this is a routing problem, why there is no problem for some servers on the same zone?

For the LAN, we just use 10.x.x.x with subnet mask 255.255.254.0.

For the DMZ, we use 10.x+1.x.x with subnet mask 255.255.254.0
