XG 330 Dropping Connection

Hi,

Last week we've been hit by BOTNET now we are rolling up some of the PC in our environment since it is windows 7.

Now we've notice that our Internet connection sometimes drop and also the ping to our branches which is connected via RED50 is also dropping.

Our CPU and Memory utilization is also high as indicated in the screenshot.

XG330

RED 50 - 20 Connections

Thanks,

Nidz

You can see that snort is running in the top processes, so there might be a misconfiguration of ips rules.

Are you using the LAN to WAN default IPS templates?

Which tunnel mode are the REDs running?

Are they running in standard/unified mode?

Please also share a screenshot of the firewall ruleset.
