Hi OpenSource-Ghost
- "Block Connections Without VPN" Does block local traffic. i.e. You can't access your wifi router on local IP.
- What do you mean by local network discovery? Accessing the local network?
- Multicast only works in a local network and is not currently blocked. See below
OpenSource-Ghost but official WireGuard app does not have any options to block local network discovery or traffic
If your Allowed IPs is 0.0.0.0/0, it blocks the local network traffic. You can hit the check mark to Exclude Private IPs. but "Block connection without VPN" will need to be disabled.
Multicast
multicast is not blocked when the VPN is on. Not sure if this is by design or not. There is currently a report on Github about it and there has been some discussion here on the forum. Multicast traffic is limited to the local network and does not go beyond the router and does not route over a VPN.
It looks like torrent local peer discovery uses multicast for discovery, so it may bypass wireguard.
If you are on a VPN, is there a reason to have local peer discovery or UPnP turned on? Just curious, I am not very familiar with torrent apps, but if you don't want it available on the local network, can't you disable that option in the app?
