Can't reach Web-Gui / Ping multiple BASE-WIRED IP's from different subnet

Hi,

I'm experiencing very strange issues with out BASE-WIRED devices.

We have multiple (16) BASE-WIRED devices with a ENV-THUM and EXP-8HUB devices connected to it. They have are running in a dedicated subnet for Serverscheck devices.
They are divided over multiple racks and connected to multiple switches.

8 of them are perfectly fine an accessible from different subnets, the other 8 are not.
They are all running the exact same firmware versions, all have identical default gateways configured etc. If I test with 2 laptops, then I can can ping sensor 1 with one laptop but not with the other one, I can ping the 2nd sensor with the 2nd laptop and not with the first laptop etc. If I am able to ping a sensor, then the Web-Gui is still not accessible.
It looks like a network issue but every single device on the network works just fine, If I configure my laptop with the same IP's as a non-working sensor, and plug my laptop to the switchport for Serverscheck, then that laptop is accessible from multiple subnets just fine. If I plug the sensor back to that same port then we have these strange issues again.

We are polling the temperature-values per sensor every 60 seconds, from another system (from another subnet) to show the values on a custom GUI on an iPad. This often is not working properly for the 8 'faulty' devices as well.

All the sensors are available when I put my laptop n the same subnet as the BASE-WIRED devices.

I've done lots of troubleshooting on the network and everything works fine, except for the Serverscheck hardware. Is there an maximum amount of active sessions to a single BASE-WIRED for example?

Has anyone experienced similar issues before? Of has any idea what is going on?

Thanks in advance!

Kind regards,

Frank

    Sounds like an issue of routing tables in your switch. If it works in the same subnet and not in a different one, then the only difference is the switch in between the different subnets. You might try to assign a different IP address to the units.
