So I uninstall and reinstall with Custom type but didn't work! Then I've uninstalled the Server Security and Agent in safe mode and reinstall normally with only difference that I didn't activate using Protect server instead I used my account to activate and now firewall is activated.
I hope ESET fix this bug ASAP.
Hey guys, I've installed the latest version of ESET Server Security on clean Windows Server today, but the firewall isn't available in setting! What should I do?
