Opera VPN background NetBIOS traffic
cy8 last edited by
Opera's VPN tries to send NetBIOS traffic on UDP port 137 by relaying it through the "System" application.
On some Windows platforms this triggers constant firewall alerts because NetBIOS traffic outside the LAN is not allowed by default. I have two questions for the developers:
Is it really necessary for the Opera VPN to send NetBIOS traffic?
Is it really necessary for Opera to use the OS kernel as proxy (which makes application control more difficult)
