Hello there, I can understand the frustration it is to go though and link up everything and make sure its running 100% correctly. With my experience with Linux and networking software, I will make sure to have this setup in no time flat for you! From verifying the configuration to the box and the multiplexer. I will make sure you leave with a smile on your face!. If you would like to further contact me, the best way would be to use the freelancer messager since I am usually on there.
Sincerely,
Daniel G.
