Why does Windows firewall block Remote Mouse?

Windows can block local helper connections until Remote Helper is allowed through the firewall, especially on public network profiles.

Should I allow Remote Helper on public networks?

Use a trusted private network when possible. Allowing helper access on public networks is not recommended for normal home or office remote control.

Does Remote Mouse need internet on Windows?

Local control can work over the same Wi-Fi network or personal hotspot without internet, but firewall rules must allow local communication.

Windows Firewall FAQ

Should I turn off Windows firewall?

No. Keep the firewall enabled and allow Remote Helper for the trusted private network instead.

Why does changing Public to Private matter?

Windows applies stricter firewall behavior to public networks. For a trusted home or office network, the Private profile is usually the right profile for local device discovery.
