I have had vbox installed on Mint for several years with guest Windows 2000. It has worked satisfactorily when accessing it from Mint and Manjaro using http and remmina.
I now have to install an updated version of Mint, so in preparation I have set up vbox on one of my Manjaro machines and transferred a copy of the vbox/guest into it.
This works fine from my other Manjaro machine but I cannot access the guest in any way, including ping, remmina/rdp, http, from any Mint machine. I have added the new IP into the hosts file for all machines - I gave the guest a new IP and made an exact copy of the remmina/rdp access record with the new IP.
Communications between Mint and Manjaro have always been troublesome to set up. Is there something I'm doing wrong? Any clues, please?
