"Multiple obects have the same IP address" with no duplicate objects

Jamie_Kelahan — Sun, 09 Nov 2025 21:29:15 GMT

I've got an issue with a gateway cluster. This started when I replaced one of my older appliances with a new one. I installed the new appliance and attempted to establish SIC, however it failed. I realized that the cluster member's IP address (in Cluster Member Properties) was set to an internal address. We used to have an on-prem management server, but now use Smart-1 Cloud, so it makes sense that SIC would fail if it's attempting to use the internal address.

I changed the IP address on the member to it's public address, but now I keep getting the "Multiple obects have the same IP address" message on this public address whenever I make a change to the cluster. Ignoring that message, I am able to establish SIC. But when I try to install policy, it "fails" after 10 minutes with SmartConsole reporting, "Installation failed. Reason: Due to a timeout value of 600000 (millisecond)." It doesn't actually fail to install - if I run "fw stat" in the CLI, it shows the correct policy installed. I should also mention that it only "fails" on the new member - it's fine on the existing member.

After the timeout message, SIC is broken again. I have to run "fw unloadlocal" in the CLI to re-establish SIC. Another side effect is that if I try to "Get Inerfaces," it fails with the message, "RunCommandInNgm('CreateNgmInterfacesCommand') failed." I followed sk154292, deleting all the interfaces and then am able to get interfaces, however I still have the same issue with the "multiple objects" message and the policy install timeout.

One thing to note after getting interfaces is that the maas_tunnel interface is populated and the existing member has an IP address defined, but the new one does not - it just says "none." I checked my other clusters and none of them have the maas_tunnel listed as an interface. In any case, whether I leave that interface or delete it, the problems still exist.

I opened a case on this, however they want to do a remote troubleshooting session in a few days. In an effort to get my HA back before I'm able to connect with support, I removed the new appliance and put my old one back in. However, the same issues still exist.

It feels like the issue is because of the multiple objects issue, but I've searched and there are no objects with that IP address with the exception of the gateway's interface. If I change the address on the original (working) member, I get the multiple objects message on that IP address as well.

As I said, I have a case open on this, but since it seems it will be a few days before I can make any progress there, I thought I'd reach out here. Thanks.

@Jamie_Kelahan please try searching again the duplicate object. Search in the object explorer or search via GUIdbedit for the duplicated object or use this older script to find the problematic object Find host objects that share the same IP-address /... - Check Point CheckMates

Thanks Wolfgang. It turns out that I actually did have a duplicate object, created by a colleague. The way it was named made me believe it was the default "eth" name from the gateway.

The duplicate object didn't have any effect on my failing policy installation nor connectivity to the cloud. That was more my own doing with taking the wrong steps to replace my old appliances. Got it all straightened out with support.

Hey Jamie,

Just for the reference, if you ever have this problem again and cant find those objects in smart console, I always recommend guidbedit. Glad you got it sorted out.
