Appliance access

NoName NoName2

Hello,

what exactly does "Appliance Access" mean.

I see that again and again in the log of the Sophos XG.

This is about the NTP port or the ports 137, 68, 67.

How do I best deal with these ports.

I found a workaround for the NTP port, but the message "Appliance Access" is displayed again.

Does anyone have an idea for that?

greeting

    Hello,
    a broadcast is a packet send to everyone within the network segment.
    So to the firewall too. The firewall handles this packet like an packet send to the firewall-IP. Therefore, you see "Appliance Access".  This Broadcast IP may be 192.168.11.255.
    Because there is no service at the firewall which "waits" for this packet, the firewall will drop it.
    Port 137 is used by Windows devices. There is nothing you have to open at the firewall.
