I would agree with Yan, EVERY PORT IS A MALICIOUS PORT. only open what you need to who you need. the router will deny the traffic by default if it is configured as a firewall.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
