Sonicwall TZ215 max connections

First, I’m not a firewall expert. For the past couple days, our Sonicwall TZ215 will start to fill up and max out the connections causing lots of problems. No internet access, unable to connect to other network devices, etc. The max is 24000.
It’s like the device is under attack. The logs don’t seem to show anything. It could be something from the inside for all I know. Where’s the best place on the firewall to look to resolve this? I have to end up bouncing it to clear the connections.

In 54min the device is up, its too many tcp connections.

Are you doing content filtering, if not, please enable and stop unproductive traffic. You might need to upgrade to higher end device.

Have you checked the hosts for virus/malwares.

Can you update the firmware to 5.9.

We do have content filtering enabled. Also, every workstation is running an up-to-date version of anti virus. How do you quantify the connections? Is there a way to determine what constitutes them?

Hi CTmountainbiker,

Yes, you can see all the connections running currently in the Connection Monitor (System > Diagnostics > Diagnostic Tool: Connection Monitor).

Let me know if you have any other questions!
