Dshield Identified Top Attackers blocks access from LAN – if your network has no internet access

Summary

The IDS/IPS security update (version 2.413) released on the 1st of October 2013 can cause the ‘Dshield Identified Top Attackers’ to block LAN traffic from 192.168.0.0 / 24. As we have identified the problem, we have now released an update of the IDS/IPS rules immediately (version 2.414). The IDS/IPS rules will then be updated automatically within the default update interval. You may need to reboot your Kerio control system to solve this problem.

    • If it is not possible to access the Kerio Control Administration – restart the server and the Kerio Control should invoke the update automatically within 10 minutes after the restart.
