UDP Port Scan McAfee firewall is blocking my new HP Officejet 6500 printer, which was connected to built-in Ethernet port in the network. Is it normal for a network Printer to do UDP Port Scan, how should I update McAfee that it's OK. Please guide me to overcome this issue.
UDP Port Scan McAfee firewall blocking Printer
Hi Emma Marie,
McAfee anti-virus software is blocking the UDP port, so to solve your problem you have to "say" that it's fine to use the UDP port. Or you can just change the anti-virus software you are using.
Since McAfee is really cautious, and for good reasons, at the moment there is only one way of solving the problem – by adding the IP address of your printer to your Trusted network list.
To do that, go to the McAfee Firewall Settings and select “My Network Connections”. Add the printer's IP. Just in case your printer is already there, try changing security levels to "work".
That should solve your problem.
