I want to run a Bitcoin node (running Knots, Electrs, Mempool) in my VirtualBox StartOS in a server PC, and use a separate client PC to run Sparrow. The Sparrow wallet will have no hot wallets-only for a connected cold wallet. For privacy and security, should I make the client PC LAN only (No internet. RPC only for the server’s Electrs)? Or is that an overkill? I know the updates will be hassle but I’m willing to do the extra tasks. I’m also thinking about running Wasabi wallet in the future but I’m not sure if I should run that in the client or server PC.
