Hi,

first thing would be update to the latest v18.5 firmware.

Yes I know. I have downgrade my version 19 to 18.5 thinking it had a bug

Hi 

Since You've downgraded your Firmware, can you check the following Link : https://soph.so/5DyyNw

There was a change in the configuration of SSLVPN IPv4 lease range. SFOS v19 uses IP subnet value while the earlier version uses IP range and subnet.

Already is good. I have migrate to v19.  Many time after, I catch the administration->Device Access https selection don't allow VPN and PING too.

Hi,

That is great to hear. Did I understand correctly that it is now okay? Only the ACL of the FW was the root cause. Thank you
