Apache, Ports, DNS2GO and ISP...

[Sephiros83]

Hi everyone,

I'm trying to run an Apache server with my ISP (Videotron, in Canada) on my PC, but I have a strange strange problem:

Only users of Videotron can access to my web site, all the others can't.

I first thought it was the port 80 that was blocked, but I've tried to change ports (with a lot of random numbers like 12345 or 3999 etc...) but it doesn't change:
customers of Videotron can access my web server, but not the others.

I'm with DNS2GO, tried the option of web redirection with the port, but nothing changed.

The DNS seems to work though, as they got in the satus bar of IE "Opening web site"
But it doesn't load anything and on my side, there isn't anything in the log of Apache.

So my question is:
Is there anything that I have misconfigured in Apache or is it possible for an ISP to:
- Find on what port my server is installed and filter every incoming request to allow only the one coming from their own compagny?

Beside, the FTP port (21) isn't blocked in anyways. Wich is kinda strange, because it's much easier to configure a FTP server than a HTTP...

Something tells me there is something wrong here but I don't know what...


Any suggestions would be greatly aprreciated.

Thanks in advance,
Sephiros

PS: I've checked my subnet mask, and it's 255.255.255.0...

see u and other user can access your own extenral ip
http://your external ip

if yes, dns2go problem
if no, isp problem

post your <url>

Are you behind a router, perchance? Have you tried pinging your dns? ping blah.myip.org? If this comes back, then try looking at the page from an internal network number 192.168.1.100 (or whatever). This should make sure your httpd is working. It's best to test each part individually. BTW, make sure when you ping your domain name, it doesn't come back with the web redirector. If it does, shut down the web forwarding feature.

It's a personnal web site, not meant to be public at all, only few friends.
Here is the adress:

http://www.sephiros.d2g.com
(or http://sephiros.d2g.com:3999)

I'm on the port 3999, my ip adress (for the moment, could change at any time but it has been stable for the last few weeks) is 24.200.169.54.

I've tried to access to the web site from local network, it works perfectly. (http://192.168.0.1:3999)

An friend (on a different ISP) tried to ping sephiros.d2g.com and he gets my IP back.
When He or I try to ping www.sephiros.d2g.com we both get "Pinging redirector.dns2go.com [63.64.164.91]"

The server is running on win98SE (yeah i know it's cheap ) with ICS activated.


Man this is puzzling...

UPDATE:

Ok i've asked to other users from my ISP to check my web site, but NOT ALL can access the web site...
Only a few.

Man I don't understand anything.

I tried to hit your page, It is resolving an IP which I am safely assuming is your routable IP (not some redirector). You have everything set to forward to port 3999?
What I don't understand is that a few people can hit your page... You have apache configured with a listen port that is the same as the one that dns2go is forwarding, and the port that your router is forwarding to...

Ex.
www redirector of 8080 (dns2go)
listen port of 8080 (apache)
forward both udp/tcp port 8080 to ip 192.168.1.X (router)

I'm assuming you've done this though, because a few people (outside your home network?) can view the page...
Please post what your network looks like... Do you have a router? Or just a 9x box connected to the 'net sharing IC? Also, the people who can hit your website, do they use the same ISP as you?

Ok, here is my configuration:

My gateway has 2 network cards.
- 1 for the local network
- 1 directly plugged in the cable modem.

This gateway runs on Windows98 SE, sharing the internet connection with ICS integrated to Windows.
There is NO hardware router of any kind (at least at home... I don't about my ISP)

The local network is plugged in a Hub.

Web redirector is set to 3999.

But now you tell me, I'm not sure I've "Listen 3999" in Apache, but "Port 3999"... does it make any differences?

And yes, the few people that can access my web site are on the same ISP as me, as I've said in the first post.

By the way, I haven't find any trace of your connection in the access.log of Apache.

-----------
I'll try the "Listen 3999" see if it works. But I remember It didn't the last time I tried...
