Kerio Personal Firewall (KPF) helps users control how their computers exchange data with other computers on the Internet or local network. Features:

· Blocks all externally originated IP traffic.
· Automatic stealth mode renders the desktop invisible to potential intruders.
· Automatically blocks all pop-up windows and banner ads.
· Detects break-in attempts by infamous hacker tools.
· Connections dialog clearly displays each application's activity at any given moment.

What's New:

· Fixed bug that KPF permitted outgoing UDP packets when relevant firewall rule was set to 'ASK'. This bug prevented KPF to pass DNS leak test
· Fixed bug that KPF blocked DHCP responses on interfaces without IP address
· Fixed bug that when KPF was configured to ask the user for both application startup and modification, it asked only for the startup even if application was modified
· Fixed bug that KPF detected new interface with address 0.0.0.0 when ethernet cable was disconnected
· Fixed bug that when KPF password was enabled, it was not possible to close application change alert dialog without knowing password
· Fixed many cosmetic and light bugs in KPF GUI
