From around 9.30 GMT this morning all client connections to the kerio box (windows with most recent v7 package) are being dropped.

We have identified the cause as the IPS rule 'Dshield identified top attackers' for which we had the action to be log and drop. Changing this to log only permits the connections.

This is preventing all connections from the internal LAN to kerio. We have lpaced the rule in log only mode but would appreciate knowing if anyone else is facing a similar situation.
Internal IP range is a standard class C 192.168.x.x

Thank you.

Same problem here. Had to switch "dshield" on logging only to make it work again.
Hope this is getting fixed fast.

Hi, Guys

Please see our knowledge base:


If you are using the 1xxx series box (the 'small' box, not the rackmounted version), you can power it off, wait for 10 minutes and you should find that the IDS/IPS signatures update themselves in this time.
