I have just bought a Thomson Speedtouch 510 and am having difficulty configuring it so that my web server is visible to the outside world. Previously I had been running quite happily for a year or so with a Speedtouch USB modem, an ADSL line, dynamic DNS using the DirectUpdate program to update zoneedit.com.

I don't really know what the problem is, as modem configuration is all new to me, but I will tell you what I have tried and what I have seen and I hope this will give you enough clues, at least to ask the right questions!

By default it seemed that when I typed the address of my site ( it would actually end up going to the modem setup pages No doubt a HUGE security hole, but hey, at least it showed something was working!

I ran ipconfig, and then from the information below I also typed in my browser and got my website. Progress! I tried putting this as the NAPT inside IP address. I also tried putting this as the NAPT default server IP address. Still I get a dns error when I type the URL so something is still not quite right. I keep reading about this stuff; the theory is making more sense but the practise is still not quite there...


Windows IP Configuration

Ethernet adapter Local Area Connection 5:

Connection-specific DNS Suffix . : lan
IP Address. . . . . . . . . . . . : 10.0.0.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.0.0.138

I tested the site on the following link:

When I run this it seems to give pretty correct results, implying strongly that things are all OK, and including most surprisingly a real page from the actual site in the 'html' returned box. So everything looks OK.

Yet when I try to surf to the site just normally, with in the browser I still always get DNS error!?!

I'm going crazy with this. I've spent days trying to get it working, and it's a real showstopper. I'd be enormously grateful for any ideas.
 
Are you trying to get to your site from your lan, or from the outside world?

Please always take the time to backup any and all data before performing any actions suggested for ANY problem, regardless of how minor a change it might seem. Also test the backup to make sure it is intact.
