Upgrading to Firmware SFOS 18.5.2 MR-2-Build380 causing internet slowness

I had the same issue. What worked for me was disabling SSL inspection. No issue since.

Thanks for the info, The only thing is SSL inspection was already not enabled :(

Hi,

disabling SSL inspection, I assume you are talking about the SSL/TLS function, if so that is not a good idea except during debugging otherwise you leave your firewall in an insecure state. SSL/TLS was implemented in previous versions. Further you need to check your services that are having performance issues because some services are not supported using the SSL/TLS rules.

The throughput issue is usually associated with IPS - DDOS settings and the recommended settings is to disable them unless you are using a server which is exposed to the internet,, then you need to tune them?

Hi , Thanks for the reply . 

Never the less, the previous version with the exact same settings was working fine with no slowness, Only after the upgrade did everything become very slow, That I had to revert back. 

This is dont think has anything to do with enabling SSL.TLS function or IPS, DDOS. 

IPS was already enabled before the  upgrade and was working fine.

Hi,

from my experience, I had to disable all DDOS settings after the upgrade because the new version was causing connection issues for some devices and I was not able to find a setting that worked.
