    I have a strange problem and can't find the solution at the moment, so maybe you can give me a hint where i have a problem :)

    First i want say the firewall is working like expected, only VPN Port is open, all others(like SSH or Proxmox GUI) are only reachable from internal network which is NATed to the VPN net.

    But i don't see any logs from the firewall at host level... for example the only logs from today are:

    0 5 - 25/May/2018:06:25:02 +0200 starting pvefw logger
    0 5 - 25/May/2018:15:48:19 +0200 received terminate request (signal)
    0 5 - 25/May/2018:15:48:19 +0200 stopping pvefw logger
    0 5 - 25/May/2018:15:49:21 +0200 starting pvefw logger
    0 5 - 25/May/2018:16:08:36 +0200 received terminate request (signal)
    0 5 - 25/May/2018:16:08:36 +0200 stopping pvefw logger
    0 5 - 25/May/2018:16:09:29 +0200 starting pvefw logger
    0 5 - 25/May/2018:17:42:17 +0200 received terminate request (signal)
    0 5 - 25/May/2018:17:42:17 +0200 stopping pvefw logger
    0 5 - 25/May/2018:17:42:17 +0200 starting pvefw logger
    0 5 - 25/May/2018:18:34:57 +0200 received terminate request (signal)
    0 5 - 25/May/2018:18:34:57 +0200 stopping pvefw logger
    0 5 - 25/May/2018:18:34:59 +0200 starting pvefw logger
    0 5 - 25/May/2018:18:38:24 +0200 received terminate request (signal)
    0 5 - 25/May/2018:18:38:24 +0200 stopping pvefw logger
    0 5 - 25/May/2018:18:39:24 +0200 starting pvefw logger
    Can't believe this, cause the only open port is the VPN port. Espeacially with log_level_in debug i expected some more logging output ;) .

    So for example if i try to login by SSH at public IP, i only want to see somewhere that it is blocked.

    Hello CSoellinger!
    Have you found any type of log file?
    I'm searching for about a few hours and haven't found anything.
    I know that there is no Live-Log-GUI like OPNsense/pfsense but a firewall.log file should be somewhere, right?

    Hopefully you or someone else have found the file.

    Best regards,

    Sorry, found it a few mins after this post:

    Has anyone found a solution to the lack of firewall logs? The log file only shows the starting, stopping and termination requests as shown by Chris above. My firewalls are working but the lack of a functional log makes troubleshooting and alerting impossible. I'm particularly interested in IPSET lists at both the cluster level and the VM level. I'm using the IPSET mail-attackers-blacklist at the cluster level as a DROP rule in my "mail services" Security Group. The configuration successfully blocks all IPs and CIDR blocks listed in the IPSET but I get no logging either on the GUI or in the /var/log/pve-firewall.log file.
