If all ports are showing STEALTH (you don't mention testing 4125, what about that one?), then something is blocking the traffic on those ports. There are several possibilities. In no particular order:
- Perhaps you didn't correctly forward the ports? This is easier than you think to do. :)
- Do you have a broadband modem that acts as a router? This would cause a "double NAT" situation with normal default configurations, and will usually lead to all ports seeming to be blocked. You can usually determine if this is a factor by looking at your reported IP address on a site such as Shields Up!, and in your router's configuration app (where it's often referred to as something like "WAN IP address") to make sure they're the same. The way to correct this is to put your broadband modem into "bridge" or "passthrough" mode.
- Your ISP may, for reasons of economy, be using private addressing on their own network. This would also lead to a "double NAT" situation.
- Your ISP may be blocking ports, no matter what they tell you.
I'm not on the WHS team, I just post a lot. :)
