Ping auf NTP Server

Harald Dunkel

Hallo,
ich nutze die Sophos UTM unter anderem als internen NTP Server. Die Sophos selber holt ihre Zeit bei drei ptbtimeX.ptb.de Servern.
Zusatzlich zum NTP-Traffic setzt die Sophos auch noch minütlich PINGs auf die ptbtimeX.ptb.de Server ab. Kann man diese PINGs abschalten?

Grüße
Harald

    Hi ,

    Thanks for the update. 

    I'd advise you to run a packet capture on UTM on that destination NTP server IP address to see the actual source of the traffic. 

    Thanks,

    the source IP is the same as the "Initiator IP" in the first screenshot -> it is the same under every black line. I just didn't want to post details about our internal network structure here.

    There are no other network interfaces in this tranfer network - only the external interface from the Sophos and a interface of our internet facing firewall. So I am pretty sure that the origin is the Sophos
