I'm pleased you got it working, but...it sounds like a nightmare to support and maintain. Very hacky, undocumented, alpha software, multi-hoop jumping.
Do you have a clear understanding of how it works, what components do what, why each is there, and a network diagram marked with subnet addresses? If not, I'd suggest you get all of those or - my real suggestion - make it orders of magnitude less complex. -- Linux Tips: https://www.tiger-computing.co.uk/category/techtips/ -- Next meeting: Online, Jitsi, Tuesday, 2020-07-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
