DNS resolution failure and VT1005

Posts: 77 · Posted: Wed Oct 20, 2004 8:20 am Post subject: DNS resolution failure and VT1005

Since I add a VT1005 to my home network, I have serious problems to access web sites on the server I run on one of my PCs. Till yesterday, I proceeded with trials and errors (lot of errors). But yesterday night I made the ultimate test: with and without VT1005.

Config 1: cable-modem -> vt1005 -> Linksys routers -> PCs
Results: The whole world BUT ME can access web sites I run on one of my PCs.

Config 2: cable-modem -> vt1005 -> Linksys routers -> PCs
Results: The whole world AND I can access web sites on my PC.
(The world and I use the same addresses like "http:// mysite.redirectme.net:8000")

Conclusion: The problem resides somewhere in the VT1005 hardware or firmware. ??? A matter of DNS resolution?

Question: what should I do to access to my web sites from my PC? Give up on Vonage? Replace the vt1005 with....????

2 Solutions. First, you could manually set your DNS servers in the Linksys Router and/or your PC. Second, if you have sufficient bandwidth, you could connect the adapter after the router: Cable-modem -> Linksys router -> PCs & vt1005. Of course you then need to set port forwarding in the Linksys for the adapter.

I'm not sure to understantd. Do you suggest to run a DNS server on my PC (Mac)? I'm not sure I can. I'm knowledgeable just enough to be dangerous.

This solution is not convenient for me. I tried it and voice becomes choppy, with delays, etc. It's a matter of bandwith as you say, I think.

No. Call your Service Provider and ask them to give you the DNS addresses. There will be 2 or 3 of them.

Once you have them, enter them into the appropriate place in the Setup screen of your Linksys Router (Toward the bottom of the page.). If you only have 2 DNS addresses, leave the 3rd set to zeros.

You can also enter these addresses in your Mac's Network Preferences Panes (in System Preferences) followed by Returns. The box looks like it only will hold 2 numbers... Just enter all 3 followed by Returns if you have them. It will hold them.

There is an error in the first message:
Config 2 should read:
Config 2: cable-modem -> Linksys routers -> PCs

It's was already done from the very beginning. After reading your post, I looked to add DNS addresses in my VT1005 settings page. So I did.

Nothing new under the VT1005: the world but me.

you have a domain right?
is not your webserver on that domain?

what kind of webserver are you using?

you must be running a webserver on one of your workstations and dont have a seperate server.

I would suggest taking the time to build a server. get something in the 1 gighrz range and get a video card with a TV out and a big harddrive.

then you have a file/web/DNS server that you can play mpegs on your tv with. that rocks.

anyway.

to fix your problem without setting up a DNS server. assuming your running windows.

find your "hosts" file. it should be in "c:\windows\system32\drivers\etc"
open the file with notepad.
it will look something like this:
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

add to the bottom of this file the local ip address of the web server and the dns name of the server.
something like this:

192.168.1.2 my.local.server

where my.local.server is the name of your webserver.
youll have to add this to each local machines host file. if you have just one machine then it is no big deal.

damn it you have a mac.

i dont know where the hosts file is on a mac but the file is going to be the same.

is should be called hosts and it will look almost identical. or most likley will.

hang on ill find it.

here you go. check this site out and it should get you going however you want.

Here is a simple experiment I conduct to verify if VT1005 can connect to virtual hosts within a local network the way a Linksys router does.

Test # 0.1 (no router and one pc)
Cable-Modem > VT1005 > The Mac on which I run my server.
VT1005 DHCP enabled, Port forwarding: 8000 TCP to 192.168.102.2
Mac IP address = 192.168.102.2, routeur = 192.168.102.1 (=vt1005)
Result # 0.1
The whole world can access any of my virtual hosts.
I CANNOT access any of my virtual hosts.

Test # 0.2 (no vt1005 and one pc)
Cable-Modem > Linksys Router > The Mac on which I run a server
DHCP enabled, Forwarding: 8000 TCP to 192.168.1.154
Mac IP address = 192.168.1.154, router = 192.168.1.1 (=Linksys)
The whole world can access any of my virtual hosts.
I CAN access any of my virtual hosts.

Conclusion ... ???
