Showing results for tags 'port 53'.
Have an odd situation. My MalwareBytes Premium is repeatedly showing blocks for an inbound IP address (we'll call it 184.108.40.206 for example) on port 53. I am running this on a personal 2008 server that does have MS DNS running and the server is behind a Cisco router that has an explicit ACL deny for 220.127.116.11/24. I've scanned the inbound connections on both the router and the server and do NOT see that IP address connected nor does the access-list show any matches for that IP being denied. Still, MalwareBytes is repeatedly blocking that IP about 50 times every 15 minutes. Any ideas where I should be digging deeper?
