[BUG] ARP attack in the new versions.

[Mishasama]

Describe the Bug It will perform ARP attacks after upgrading to 17.2.1. My PC has detected the phone keeps broadcasting its MAC with the router's IP. This makes all devices lose connection.

To Reproduce Steps to reproduce the behavior:

1. Start VPN (Use direct connection to tor)
2. Wait it connected
3. Wait about 5~15 min
4. Check any device or route log, you will see the ARP attacks

Expected Behavior What are you doing?

Just to clarify, you are saying that OTHER devices on your local area network are seeing an ARP attack originating from your Android device, only when the Orbot VPN is activated?

Also you mentioned 17.2.1 (old) above but then say you are running 17.3.2 RC1 (latest)

Did you make any changes to Orbot settings? What is the router/IP space of your local area network? Perhaps it is the same as the Orbot VPN virtual LAN?
