GRC Leaktest

When I apply the leak test,result is firewall penetrated.
How do I correct this in comodo firewall?

Hello!

What mode do you use for the firewall? Also, please double-check that there’s no entry already for leaktest.exe in FirewallAdvancedNetwork Security Policy. When you launch the application, you should get this alert from the firewall, which must be blocked.
