What strange rules suddenly appeared in iptables?

Question

linux

Hello everyone, help me understand.
Server on CentOS. installed 66th WHM
tonight strange firewall rules appeared:
DROP tcp -- anywhere server.***.com tcp dpt:irdmi /* KOP-315-65406 */
DROP tcp -- anywhere server.***.com tcp dpt :webcache /* KOP-315-65406 */
DROP tcp -- anywhere server.***.com tcp dpt:https /* KOP-315-65406 */
DROP tcp -- anywhere server.***.com tcp dpt :81 /* KOP-315-65406 */
DROP tcp -- anywhere server.***.com tcp dpt:http /* KOP-315-65406 */
The comment next to each rule is very interesting.
couldn't find anything on google.
perhaps the HG firewall plugin installed in WHM influenced, but there is nothing like that ...

It looks like KOP-315-65406 is the number of a ticket or request in your hoster's support, try contacting them.
