Tailscale version 1.18.0 (uptodate)
Windows 11 21H2 (uptodate)
I’ve been using tailscale for a while now, véry happy with it. Last weekend I purchased a subscription to ProtonVPN. It’s very configurable, including split tunnel.
However; when protonvpn is active, I can’t use rdp (port 3389) to connect to a remote machine through tailscale. As soon as I disconnect, it works fine.
I’ve configured protonvpn to use the openvpn protocol instead of wireguard, I’ve excluded the target ip, I’ve excluded the tailscale binaries, I’ve excluded the entire tailscale subnet - nothing.
The weird thing is: I can ping the machine on its tailscale ip. I can also connect to http servers on other tailscale-connected machines, but rdp doesn’t seem to work on any of them.
I’ve just tested with ftp, and that doesn’t work either. It feels random, does anyone know a technical reason this is happening?
