I have been given a pair of sr2600 intel server antiques with two xeon x5675 and I would like to connect these 2 together with a third machine. I've installed proxmox 8.2 ve non-enterprise on both and the third is only got debian bookworm on it. They all have internet and can I suppose use that as a connection to each other. I am a total noob and realizing I am asking for more than to be expected but hoping for mercy. I have proton vpn installed on each and this is all just for home use for each family member to have a common place to put pictures and files that can be secured.
