Ok. I am deffinetely not an expert with networks... Not even a begginer. I am a PLC self-made programmer (I am an engineer that had to turn into a programmer due to family problems); so I lack a lot of basic stuff to know. I am facing the following problem:
I have a network (10.0.0.xx) with a PLC, a few HMI's and a PC, a printer, and other things. And the corporation where it is installed, dont want me to bring all of these devices into their network (192.168.0.xx); they just want to "see" my PLC, which is 10.0.0.60; They gave me an IP for it: 192.168.0.153 and they want to access it through this particular IP (I have to make a master-TCP Modbus protocol to communicate, but that's no problem once the network prolem gets solved). I guess they will tell me which IP is going to be the SLAVE in the TCP communication; lets guess 192.168.0.156 i.g
So the thing is: I want to be able to ask and get answered from the outside and vice-versa (open communication) but it HAS to be ass told: They will search for 192.168.0.153, and 10.0.0.60 will answer; and i will do same with 192.168.0.156 from the 10.0.0.60.
As a really really noob; I lost the day yesterday following many tutorials about NAT with srcnat and dstnat; and so far no luck. What I've done so far:
Ethernet 1--> Set to IP 192.168.0.155
Ethernet 4--> Set to IP 10.0.0.96
Tried many combination of NAT IP filter rules without success. What I try to test the connection, is pinging 192.168.0.153 from the 192.168.0.xx subnet with a PC. I set my own PC with that IP (192.168.0.156) to make the test.
Any help; please¿?
