Can you explain why this is happening?.....(Domain name vs IP address)

I have (2) Windows 2000 Pro PCs which is connect to Linksys DSL/Cable router.

One of the PCs act as a server and I use DNS2go to forward the address: geekforum.d2g.com to xx.xx.xx.xx (my roadrunner IP address). Of course, I set the router table in Linksys to forward port 21 and 80 to 192.168.x.x (my server).

This is what happened:

If I type the address (geekforum.d2g.com) on my computer or the server computer...it would work for a few seconds and then, I can't access the internet anymore unless I reboot the computer. The roadrunner IP address works fine and no hangups whatsoever.

Hangups only happened when using my domain names like geekforum.d2g.com and neoverse.net which is forward to my roadrunner IP address. Why?

Does typing the domain name that belong to me confuse the Linksys router?

Thanks for any help.

 
Yes, your router is getting confused...I think it's trying to route your session out it's interface, and then back in again, and it's screwing it up.

Don't use DNS to get to your own server--put an entry in your hosts file for your servers, matching it up to your INTERNAL (real) address for the web-site. That way, you won't hit the DNS and get the EXTERNAL address of the router, but the real address of the server.

--Woodie
 
Thanks.

Can you explain a little about the entry in the host file? An example?

The problem is I'm trying to run a forum off my server as an experiment and I have to enter the URL address of the server in the forum setting files.

That really mess it up.

 
I forget where the file is located, somewhere in your WINNT directory. Do a search for "hosts" inside C:\WINNT (and subfolders) and at the bottom of the file, add:

xx.xx.xx.xx geekforum.d2g.com

There should be lots of commented-out examples in the top of the file to tell you how to do it.
 
I just tried that and it doesn't help.

This is what I added:

127.0.0.1 localhost
xx.xx.xx.xx geekforum.d2g.com
xx.xx.xx.xx neoverse.net

The xx.xx.xx.xx is the roadrunner IP address.

Should it suppose to work? I tried and still hangs.
 
I believe that the Linksys routers have the same problem FreeSCO has. You cannot initiate a connection to an IP address that will be routed back into your network. I would check for a fix for this on Linksys' site, or do not use your Internal DNS server. If you have a Netgear one, that will work just fine.
 
So, it is a flaw with Linksys router?

Is there a name for that? The ability to go to the internet and back?


I've been planning on getting NetGear router because Linksys doesn't seem to handle high speed download.
 
**UPDATED**

Thanks, Shadow07.

The firmware did the trick. I can now use the domain name without any hangups whatsoever. It seems faster too.

Thanks everyone for your help. 😉
