Yes i've a LinkSys WRT54G router and i'm using DynDns.org as dynamic IP "handler",

And yes my ISP Videotron is blocking .. well at least one port the 80, that why my IIS is configured on the 8080, but it no longer work by now ...

Is there a way to know where a port is block ? I meen if the port is block by my ISP or by a bugged router
