Since I'm not doing this thing for the first time, I've done all the things u mentioned earlier itself. Thing is , I had to switch from port 8080 because I was getting forwarding errors 2 weeks ago even though every thing was done properly. I tried WebUI access from my place but it didn't work. I realized that it was because of the Java server running on the same port I wasn't able to access it but strange thing is that when I tried to access it from my computer center using my DynDNS name, it worked. Now after changing the port number, it is not accessible either locally(in LAN thru direct IP) or remotely(via DynDNS name) while the HFS server running on the port 1947 is running fine and is accessible too.
