firewall lockup and slow/disconnects sslvpn
We recently got a sonicwall firewall + 2 switches. The firewall has been running for 2 months without any problems. But this morning I got to work and it just crashed. I had an update schedule ready in Azure, which also failed. A firewall shouldn't crash that's the last thing I want to spend my time on. We have these products SONICWALL TZ 370 , SONICWALL SWITCH SWS14-24FPOE, SONICWALL SWITCH SWS14-48. We have a small number of vlan's with default access rules nothing special. I also bought some capture client licenses last week. I installed this on all endpoints, including the servers. Today I uninstalled it again from the servers. (After installing we got lockups with rdp connections in combination with sslvpn) We also suffer from slow sslvpn connections. I've already set dpi to preformance but to say that it makes it much faster NO. All in all, I have not had a good experience with SonicWall at all. I would have been better off buying a simple soho router for a few euros.
Now my question is there a chance that it will really become more stable after a firmware update on the firewall or is that just a waste of time?
