Modbus comm with EGX100 Ethernet gateway

I'm trying to read Modbus RTU slaves from a Schneider Electric EGX100 Modbus TCP/Modbus RTU gateway from my PC using the various Modbus polling software available.

I know that the communication works fine because I can access the on-device web server and read the slave device registers fine from there.

I just don't seem to be able to read via a generic Modbus TCP link. Is there any other setting that needs to be done in the gateway to enable Modbus TCP communication.

I've configured the gateway at 169.254.0.10 and try to access it using Modbuspoll and SimplyModbus but just can't connect on port 502.
