SpliceVPN links your devices into one private, encrypted network. Install it on each device, share a single key between them, and they reach each other as if on the same LAN.
Download and run the installer — it sets up WireGuard and the SpliceVPN agent, then asks you to create or join a network.
Download the Windows installer — or, in an Administrator PowerShell:
iwr https://splicevpn.com.au/install-splicevpn.ps1 -OutFile $env:TEMP\splice.ps1; Start-Process powershell "-ExecutionPolicy Bypass -File $env:TEMP\splice.ps1" -Verb RunAs
sudo apt install -y wireguard curl -fsSLO https://splicevpn.com.au/splice-agent && chmod +x splice-agent sudo ./splice-agent # asks to generate or paste a key
A network key ties your devices together. The first device generates one; every other device pastes that same key to join.

A device can be on several networks at once — say your home mesh and a work mesh. At install time just answer yes to "Add another network?" and paste or generate another key. Each runs as its own tunnel with its own address range, so they never clash.
192.168.1.0/24). SpliceVPN refuses with a clear message. Fix it by renumbering one side, or connect just the single host instead of advertising the whole subnet.Install WireGuard first — the Windows one-click installer does this for you; on Linux run sudo apt install wireguard.
Devices connect directly, which works on the same LAN or when one side has a public address. Two devices behind separate home routers may not connect directly yet — relayed connections are on the roadmap.
See the rule above: two networks with the same LAN range can't be bridged.
