Can you explain a bit what do you mean by “input filters” ?

If you refer to a bi-directional blocking, it either blocks everything or passes everything. It’s not like a router or Windows firewall where you can independently block incoming or outgoing connections.

Also, make sure you properly configured Global Pre- and Post- filters in the app. The order of execution is:

1. Pre filters (rules)
2. App filters
3. Post filters

Also, since it creates virtual VPN connection and routing, you won’t be able to share WiFi access point on your phone with other devices connected to it while the firewall app is running. Maybe that’s the problem in your case. Sorry, I don’t have a solution for it.

Come apps cannot work with firewall enabled, so I can’t really help you with this issue. Contact developers and explain the issue, they might be able to help, or at least offer explanation.

I suppose you configured firewall app properly, but you can also try setting up a pre-filter (fourth icon at the bottom) to bypass it on local networks.

Please help me…. To get KDE Connect to work over my local network
