SOME/IP and VSOMEIP - Communication between 2 devices (TCP/UDP) Not working

I am working on Franca IDL and trying to implement the SOME/IP two device communication. I am referring the below links:

1. https://at.projects.genivi.org/wiki/pages/viewpage.action?pageId=5472320
2. https://github.com/GENIVI/vsomeip/wiki/vsomeip-in-10-minutes#request

Current Setup:

Ubuntu 18.04 (two machines - Server & Client) Two Machines connected over ethernet

But am actually confused between SOME/IP and VSOME/IP. Anyhow I went with the link [1] I could able to achieve communication between the processes running on the single local machine. I failed in two 2 device communication.

Later I followed the same in in link [2] but even here I was able to achieve communication between the processes running on the single local machine. I failed in two 2 device communication but server was running in one device and client was running on another but no communication achieved.

I came across this VSOMEIP - Communication between 2 devices (TCP/UDP) Not working post here but couldn't get how to proceed further.

My actual aim is to achieve two device communication using Franca IDL and SOME/IP i.e link [1]. But I am not finding any single source so that I can at least look into it.

Any suggestions will help me a lot. Thanks in advance.
