Availability Group causes hundredthousands "echo requests a day"

Hi,

a recently installed sophos utm (sw:9.355) generated about 400k of echo requests a day. In the availability group, I set the setting to query udp/53 for dns server verification. But it also makes pings, even I didn´t configure it. Now the provider asks, why our devices are generating such big amounts of pings....

Is it normal, that the availability group always creates icmp requests, additional to that setting, I made? Its strange, because it is the first time, I got an information about that. But in this case the dns servers aren´t replying to icmp requests.

If yes, is the only possibility to create a firewall rule to block that or what can I do?

Best Regards,

Sebastian

All,

This is a known behavior in UTM and considered normal as far as nothing is effected. This is taken into consideration under NUTM-4760 but unfortunately, there will be no change as of now.

Thanks for the patience.
