Hi bill001g
Thanks for your detailed response. You are correct it is the routers as previously mentioned it is a WAN scan I'm scanning using nmap set up to scan ALL 65535 ports - BuddhaSkoota- I'm doing the test right. I get no responses from every other port but on BOTH networks the SAME THREE PORTS respond as closed. That is one hell of a coincidence. Especially since none of the three are the common ports like 80 or 443. COULD IT BE THAT A COMPUTER ON EACH IS NETWORKED TOGETHER THUS CREATING THE ACK RESPONSE AND EXPLAIN WHY IT'S THE SAME 3 PORTS ON BOTH NETWORKS? That's all I'm asking. What are the situations in which the same three ports would be responsive on two different networks, assuming obvs that a VPN or skype or xbox live or something is joining them
