I'm unable to open website internally as well as externally. I have UTStarCom ASDL Router and also did port 80 forward.

Can someone tell me why its not working?

You don't give us anywhere enough information to help you. Frankly, you really will probably need to list the full DNS name. – KCotreau Jul 17 '11 at 22:45

OK, the first thing you need to make sure of is that your Router or other method of updating your DDNS is working.

I did and NSLOOKUP of your domain and it points to So now on one of your computers, go to and make sure it matches that IP address.

If it does, you have a router configuration problem. I could not telnet 80 so as of now, the port is actually closed on that IP address.

I would make sure that you have a static IP address set internally for the port forwarding, and then see if you can figure out what is wrong with your port forwarding configuration.

If you post back some screenshots of the appropriate areas, and the exact model of your router, I can try to guide you more.

I have attached few screenshots, also my ISP changes IP address dynamically, its not static, As per I have installed dyndns updater to support dynamic ip. Again RouterName = UT300R2U, Its a asdl router (utSTARcom ) – user7044 Jul 20 '11 at 14:44
I asked my friend to upvote your question, so in the future, you can just click the little image icon (in edit or new question mode), and upload your pictures directly into the question. – KCotreau Jul 20 '11 at 14:59
OK, your DDNS part is definitely working 100%. I was also able to get to port 80 ("It works!" was displayed). What is still not working specifically? Or what are you trying to do exactly/ – KCotreau Jul 20 '11 at 15:05
well when I try to do the same inside of my LAN network it doesn't work. I don't see any response. Is it because the router blocks the external ip. – user7044 Jul 20 '11 at 16:53
