[Cant connect to plc remotely ?]

Thanks for trying to help and sorry for the late answer,There was an issue with port forwarding everything is ok now.

[Cant connect to plc remotely ?]

Hey there im new to plc programming and I have tried to make an application witch could control the plc remotely .

Ethernet ethernet = new Ethernet("*REMOTE_IP*", 20256, EthProtocol.TCP, 3, 3000);

Now when im on the same network[same router] as the plc everything goes fine but once I try to reach it from a different network Im getting an exception at this part.

 

I have opened the 20256 and 20257 ports on the router and it still didnt worked.

 

 

any idea what might be wrong ? is there a chance that the plc it self reject the remote connection ?

 

*PLC model - V1040-T20B

 

Thanks in advanced
