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

    Hi ,

    Thank you for reaching out to Sophos Community.

    Moving this thread to Sophos(XG) firewall.

    Port 137 is for the NetBIOS traffic. Can you please share the snapshot of the events with ports 67 & 68?

    Hi,

    I have logged this issue in previous threads and still see it. Sometimes the device that is requesting the DHCP address is identified other times there is not device in the logviewer entry. Further the device that is being rejected has a static IP address, but does a release and renew every 10 minutes after it has posted the latests data to the server.

    Port 137 means you have MS protocols active on your network which are broadcasting and the XG rejects them.
