I have a small home network which I am attempting to secure with a Netgear FVS318 firewall router. I have a total of 3 PC's on the network running Windows ME, Windows XP Home and Windows XP Pro. I am considering adding a Linksys BEFSX41 firewall router after the FVS318 as an added layer of protection. I do not run any software firewalls on any of the machines, all firewall functions are done by the router. The problem is that I am finding unknown open ports. The port numbers are 5870 and 15101. I am seeking assistance in identifying the ports. For the time being, I have blocked them through the router being that I do not know what they are.
