I need a software to monitor open ports on my network based on my internet IP address. I've used programs in here but they scan my LAN. I want to scan my WAN to see which ports are open and which aren't based on my internet IP, not my internal or router's.
Requirements:
- must scan all ports (not just a subset)
- must work "from the outside" (i.e. scan the WAN interface, not the local network)
It's useful when, for example, you want to check whether Bittorrent, Proxy etc. ports are currently blocked by ISP or not. thanks.
