Hi everyone, Im newbie here. A few days ago after years of using astaro I upgrade my firewall to sophos UTM 9. I realized that after some time of users inactivity (not browsing the net) sophos get to some "offline phase", and I cant get to internet nor to internal NAS. Ping is OK, DHCP is working but I cant make RDP to other PC into LAN neither browse the web. Any ideas how to repair that? thanks,
