I was able to host servers back in v13, but now I cant. My WRT 120N Cisco/ Linksys router had UPnP on by default. I tried hosting a server in v14 with the old port forwarding settings & UPnp on but I still get --- ping. I am also running Windows 7 x64 and Kaspersky 2010.
UPnP options I found-
Administration
UPnP: (Enabled) Disabled
Allow Users to Configure: (Enabled) Disabled
Allow Users to Disable Internet Access: Enabled (Disabled)
