Re: BZ Kerio 2x Default Replacement Update

In your advanced rules under zero octet rule are these rules really only necessary for LAN connections? Are they really rules to block ad servers or just to prevent spoofing for LAN connections?

Re: BZ Kerio 2x Default Replacement Update

They are not ad-blocking rules by any means, but are meant to block packets which could have a spoofed source ip address. The anti-spoofing rules are used for private/unused ip ranges which should not be used over internet connections. If you do run a lan, the allow rules when enabled, and configured correctly for your setup will compensate for these blocking rules before they effect your connections.

As an example some have found they are getting packets from 192.168.0.100 when they are not even on a network of any kind, and the packets are actually messenger spam targeted towards udp port 1026. This way you can't trace the real source, and if it got through you might see a messenger window on your desktop advertising something.
